Damselfish-assisted repair of wounded corals surprises scientists
- A new study finds that a coral-associated damselfish may help hasten the healing of wounded corals.
- The research showed a 55% faster recovery rate from larger coral wounds in the presence of damselfish, and a 38% faster rate of healing for smaller wounds.
- Algae living within wounded corals exhibited decreased photosynthetic efficiency, an energy source vital to coral healing, when damselfish were absent.
- Scientists say the findings could inform conservation management plans, focusing more attention on preserving fish habitats to better protect corals.

Namibia greenlights controversial project to dredge phosphate from seabed
- Company Namibian Marine Phosphate has received an environmental clearance for dredging within a concession that spans 2,234 square kilometers (863 square miles) of the Atlantic seabed off Namibia’s coast.
- The company wants to mine phosphate rock, a major ingredient in fertilizers, which has previously only been commercially mined on land.
- The nonprofit Ocean Conservation Namibia (OCN) has strongly criticized the decision to issue the ECC, warning “that the large-scale development could have significant impacts on the Benguela marine ecosystem, Namibia’s fishing industry, and marine conservation.”
- NMP, registered in Namibia, is 85% owned by Oman-based Mawarid Mining LLC and 15% owned by a Namibian company, Havana Investments (Pty) Ltd.

Gulf of Mexico’s unique Orca Basin shouldn’t become a carbon dump (commentary)
- Deep in the Gulf of Mexico, an ecosystem exists in water so salty and lacking in oxygen that its marine life is unique and virtually unstudied.
- Called the Orca Basin, it’s now the focus of a corporate effort to profit from fighting climate change by dumping tons of organic waste into its depths, a deep-sea biologist explains in a new op-ed.
- “The Orca Basin is not a waste repository waiting for a use. It is a living system that has been developing for thousands of years, hosting organisms we have barely begun to characterize, preserving a chemical and biological record we have barely begun to read,” the author argues.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

Scientists use satellites to track whale strandings in remote places from space
- In the early 2000s, attempts to track cetaceans from space yielded only unidentifiable dark blobs; now, very high-resolution satellite imagery allows researchers to pinpoint specific whale species from orbit.
- This optical satellite technology provides access to remote parts of the world’s oceans, helping scientists establish vital baseline data on whale mortality trends, sea surface temperatures and ocean currents.
- Researchers emphasize that satellites will supplement, not replace, traditional field-work, as data quality remains vulnerable to environmental limitations, including cloud cover and heavy winds, and to satellite availability.
- Scientists are building global networks to improve consistency in data collection and are advocating for increased access to satellite data to better understand causes of whale strandings around the world.

Global sea surface temperatures reach a record high, again
Global sea surface temperatures have reached a record high, raising serious concerns for global Earth systems, according to new data released by the European Union’s Copernicus Climate Change Service (C3S). On Aug. 22, the daily global average sea surface temperature, outside polar regions, reached 21.1° Celsius (69.98° Fahrenheit), exceeding the previous record set in March […]
Blast fishing destroys reefs. Underwater microphones can help detect it
- Once home to a pristine and vibrant network of coral reefs, the Spermonde Archipelago off the coast of South Sulawesi in Indonesia has had its coral decimated by the illegal practice of blast fishing, in which improvised explosives are tossed into the sea to kill and stun fish en masse.
- A new study harnesses acoustic data to produce what is likely the first rigorous estimate of the frequency and intensity of bomb fishing in the archipelago.
- Using low-cost microphones and an easy-to-run algorithm, the researchers detected more than 3,500 so-called fish bombs going off in their study area within the archipelago — an average of 23 blasts a day, or almost one every hour.
- The scientists believe their approach could help communities and NGOs around the world design targeted interventions to combat the practice, which can devastate not only reefs but the broader marine ecosystems.

Scientists discover 149 new deep-sea species at remote Indian Ocean seamounts
- A new study details a deep-sea expedition near the remote Christmas and Cocos islands, where researchers visited unexplored seamounts and identified 149 previously unknown marine species, including black corals, sea worms, sea cucumbers and a variety of fish.
- At a site they dubbed “The Shark Tooth Graveyard,” researchers discovered around 1,000 shark teeth, covering more than 22 million years of evolution.
- Researchers from institutions in Australia, New Zealand, Canada and the U.S. surveyed the seafloor down to 5,431 meters (17,818 feet), where conditions are cold, dark and high-pressure with limited food options for benthic species.
- Deep-sea research is notoriously challenging, but scientists stress the importance of exploring these ecosystems as they face growing threats from warming oceans, pollution, overfishing and deep-sea mining.

El Niño is disrupting the Pacific’s marine food web from the bottom up
As the 2026 El Niño strengthens in the equatorial Pacific, satellites are capturing the first major signs of disruption to the marine food web. According to by NASA’s Earth Observatory observations, satellite measurements show a substantial drop in surface concentrations of chlorophyll across the Central Pacific compared with neutral conditions in June 2025. Chlorophyll is […]
In Raja Ampat, children learn that their knowledge can help protect their islands
- Research suggests that children who grow up closely connected to their surroundings can develop sophisticated understandings of their local environment.
- A recent children’s book reading was part of a gathering of Indigenous communities in Arborek that brought together representatives from 20 Indigenous subtribes in Raja Ampat, as well as Indigenous people from other parts of Indonesia and abroad.
- The book turns the biodiversity of Indonesia into a visual story about what could be lost if mining damages the environment.
- The author and illustrator hope that seeing their home, animals and stories represented in a book will encourage the children to tell more stories of their own.

Antarctic krill fishery closes months early amid increasing fishing pressure
- The krill fishery in the Southern Ocean has closed more than three months early after reaching its annual catch limit of 620,000 metric tons — a precautionary quota established to prevent overfishing.
- Krill forms the foundation of the Antarctic food web, with penguins, whales, seals, fish, squid and other animals depending on the tiny shrimp-like crustacean.
- The early closure of the fishery is linked to the growth of the krill-targeting fleet, as well as to what some scientists call an “unprecedented” concentration of fishing activities in areas where krill is most abundant.
- Scientists are raising concerns about the combined impacts of overfishing and climate change on both krill and the Antarctic and Southern Ocean wildlife it nourishes.

A deadly cross over: In South Africa, rabies moves from land animals to seals
- Cape Town, South Africa, has recorded 135 incidents of aggressive seal behavior toward humans since September 2021, including injuries that led to hospitalizations.
- Researchers suspect the cause is rabies, a disease normally associated with land animals but has leapt to Cape fur seals.
- Since May 2024, rabies cases have been confirmed in Cape fur seals along the Western Cape and Northern Cape coastlines of South Africa — the first time the virus has established itself in a marine mammal population anywhere in the world.
- Beyond attacks on humans, researchers worry whether the disease will spread to other marine mammals, as seals interact with different species.

Indigenous fishers rethink shark hunting & protect species on Colombia’s coast
- In the Colombian department of La Guajira, at South America’s northernmost tip, Indigenous Wayuu fishers from the community of Punta Gallinas are working with marine biologists to conserve and document shark populations.
- Despite a 2021 law banning targeted shark and ray fishing in Colombia, the meat remains a vital protein source in one of the country’s most remote and food-insecure regions.
- Colombian shark conservation initiative Proyecto Puyuii is working with Wayuu fishers to record shark species in the understudied waters of La Guajira, implementing sustainability measures such as larger-mesh nets, safe release techniques and avoiding longlines.
- With sustainable tourism touted as a potential economic alternative to shark fishing, some fishers argue that compensation will need to be offered before they can afford to stop.

Dolphin mother and calf observed using shells to catch fish in Australia
A small population of dolphins in Shark Bay in Western Australia have a documented history of using an unusual tool to help them catch fish: Large, empty snail shells. For the first time, scientists have now observed the same behavior in a different dolphin population on Australia’s east coast. Researchers even filmed a baby dolphin […]
Mobile queen conch hatcheries strive to help the species, engage Caribbean communities
- International demand for queen conch meat and shells has led to severe overharvesting, while habitat degradation, pollution and warming waters add further threats.
- In a bid to slow the decline of the queen conch, researchers are partnering with local conservation organizations across the Caribbean to establish a network of mobile hatcheries aimed at protecting the giant marine snail through its vulnerable early life stages.
- The goal is not only to nurture developing conch, but to create community spaces where local people can learn about the queen conch life cycle and participate in restoration efforts.
- However, some researchers have doubts about whether aquaculture alone can restore wild conch fisheries.

Global marine protected areas fail to safeguard most sharks and rays: Study
- Marine protected areas (MPAs) cover less than 10% of the ranges of most species of sharks and rays, with significant shortfalls for threatened and critically endangered species, a new study finds.
- The analysis also reveals major gaps in reporting on the extent of fishing and harvesting re-strictions in these preserves.
- The study’s authors recommend including biodiversity targets as part of the 30×30 framework and encourage policymakers to consider aligning MPAs with important shark and ray areas to maximize conservation and biodiversity benefits.
- However, some researchers disagree that blanket MPAs would meaningfully benefit shark and ray conservation.

Iceland to deport antiwhaling protest ship’s crew after they interfered with whale hunt
- Authorities in Iceland have detained an antiwhaling protest vessel and its crew after it interfered with a hunt by Hvalur hf., the country’s last whaling company.
- The M/V Bandero, operated by the Captain Paul Watson Foundation, and its 21 crew members were being held in Reykjavík; authorities have ordered the crew’s deportation, with five Americans deported on August 6.
- Iceland is one of the few countries in the world that still commercially hunts whales, with a quota this year of 150 fin whales; in 2023, Hvalur hf. killed 24 fin whales, and the year before, 148. As of Aug 7, at least 35 fin whales have been killed, according to the foundation.
- The fin whale is one of the world’s largest animals and is classified as vulnerable on the IUCN Red List, with about 100,000 mature individuals remaining worldwide.

Gabon ends fisheries partnership agreement with EU
Gabon has ended its 19-year fisheries partnership with the European Union, which allowed EU industrial vessels to target tuna in Gabonese waters in exchange for payment, arguing the agreement no longer serves the country’s economic interests. The decision follows a June 2025 Council of Ministers meeting at which the government announced it would seek to […]
As Canada’s captive belugas arrive in the US, questions linger about their future
- Thirteen beluga whales from a pod of about 30 languishing in the shuttered Canadian marine park Marineland arrived in the U.S., six of them on July 21, and seven on August 3, as part of an emergency rescue of these captive cetaceans.
- The transfers come after nearly a year of jostling between the Canadian government and Marineland about the belugas’ future, amid threats of euthanasia and disagreements over where the cetaceans should be housed.
- Earlier this year, several U.S. aquariums drew up an emergency rescue plan to transfer these cetaceans to four U.S. facilities.
- Conservationists say the U.S. move leaves questions unanswered about the cetaceans’ future, including if they would be used for entertainment or bred in captivity — both outlawed in Canada since 2019.

How social media and parrotfish poop are protecting the Maldives
- Parrotfish play a vital role in reef ecosystems by producing sand from consumed coral and maintaining healthy reefs by grazing algae; in doing so they support the sediment accretion processes that help low-lying atolls naturally grow and adapt to rising sea levels.
- A grassroots social media campaign in the Maldives raised awareness about the ecological importance of parrotfish, helping build widespread public support for their conservation after the species began proliferating in local fish markets during the COVID-19 pandemic.
- Public backing from the #FishForTomorrow campaign led the Maldivian government to ban the catch of all parrotfish species in 2020, making the Maldives one of the first countries to enact national protections based largely on community advocacy.
- Building on this success, the NGO Maldives Resilient Reefs is expanding conservation efforts through sustainable fishing partnerships, seagrass protection and a nationwide initiative to protect 30% of the country’s marine habitats by 2030.

On a Philippine beach, villagers are stepping up to save sea turtle nests
Beaches in San Vicente municipality in the Philippines’ Palawan province are crucial nesting grounds for olive ridley sea turtles. But the turtles and their babies face perilous journeys on those beaches — from dogs, tourism, and increasingly severe storms and high tides. To counter these threats, the NGO Large Marine Vertebrates Research Institute Philippines (LAMAVE) […]
What happens after a whale strands on a Mumbai beach?
On the morning of June 27, a 7.6-meter (25-foot) blue whale calf washed ashore on a busy beach in Mumbai, India’s financial capital and the capital of Maharashtra state. Whale strandings are rare along the Maharashtra coast, so Mongabay spoke with experts to find out what happened next. “Each stranding incident is a totally unexpected […]
Scientists discover that giant octopuses were top predators of ancient oceans
Finned octopus species alive today are all small, deep-sea animals that mostly live in pitch-black darkness thousands of meters beneath the surface of the sea. But a new discovery by a team of researchers in Japan, published in April 2026, found that the ancient octopus relatives were likely gigantic predators that roamed the late Cretaceous […]

Papua New Guinea, Vanuatu, and Fiji announced the Melanesian Ocean Corridor of Reserves in May. Solomon Islands joined in […]
Deep-sea snails and mussels in Indian and Pacific Oceans contain microplastics, study finds
- A new study has found microplastic particles in almost all sampled mussels and snails inhabiting deep-sea hydrothermal vents in the Indian Ocean and southwestern Pacific Ocean.
- By comparing snails and mussels from hydrothermal vents in two oceans, researchers found stark differences in levels of microplastic contamination between the two.
- The new study suggests the animals’ different feeding mechanisms might influence the amount of plastic pollution in their bodies.

Coral reef experts press on, with climate looming over international conference
- Coral reef scientists, conservationists, policymakers and community leaders from more than 90 countries met July 19-24 at the International Coral Reefs Symposium in Auckland, Aotearoa New Zealand.
- Participants discussed how to combat the drivers of climate change, how to characterize and communicate the current condition of coral reefs, and how to empower Indigenous communities and integrate their knowledge systems, among other topics.
- During the week of the conference, a new U.S.-based coral reef research center was launched and the first-ever high-resolution mapping of living corals for the Pacific Ocean was announced.
- The next International Coral Reef Symposium will take place in Rio de Janeiro, Brazil, in July 2030.

Drifting tuna fishing gear enter half of marine protected areas: study
- A global study estimates that drifting fish aggregating devices, or dFADs, affect more than half of the world’s protected marine area.
- Researchers documented at least 6,324 dFAD strandings across 174 protected areas in 53 maritime jurisdictions over a period spanning 2007-2023.
- The analysis found no clear evidence that fishing fleets systematically concentrate dFAD fishing around large marine protected areas.
- Researchers and an independent fisheries expert are calling for stronger limits on dFAD deployments, better tracking and for companies to have greater responsibility for retrieving lost devices.

Wind farms join bottom trawlers and oil rigs in a protected North Sea sandbank
- Dogger Bank is a vast, shallow sandbank in the North Sea that was once among the most productive marine nurseries in Europe, prompting experts to call it the ecological heart of the North Sea.
- While much of Dogger Bank has been protected for its unique seabed habitat, destructive industrial activities like oil and gas extraction as well as fishing practices like bottom trawling have continued, even in the protected zones.
- Now, conservationists have notched a win with a recent court ruling that curtails bottom trawling in Dogger Bank.
- However, they say the threats continue, notably in the form of major wind farm developments rising in a protected area.

Extreme weather dampens breeding success for marine predators in Tasmania: study
- A recent study found that extreme weather events like storms, heat waves and floods can interfere with the breeding success of marine predators like seals, shearwaters and albatross that raise their young along the coasts of the Australian state of Tasmania.
- While some colonies appeared unaffected by extreme weather, others saw offspring swept away by powerful waves and storm surges, hypothermia during unusually wet episodes, and deadly overheating during periods of high temperatures.
- The researchers noted that these extremes are among many challenges seals, seabirds and other marine predators face, including pollution, disease and declining food supplies, which can also be influenced by extreme weather events.

Finning the High Seas

In celebration of World Mangrove Day on July 26, the U.S.-based Mangrove Action Project (MAP) has announced the winners of its 12th annual photography awards. “Mangroves are the underdog. They will never be as glamorous as the Amazon rainforest or coral reefs. But through photography we can change that narrative, and intrigue people by showing […]
One scientist’s mission to save Ghana’s disappearing guitarfish
- Fishers from Ghana travel the length of the West African coastline to find the richest fishing grounds, but the availability of this vital source of protein is under threat from a number of sources.
- Declining catches of bony fish like tuna and mackerel have put elasmobranch populations — sharks and rays — under increasing pressure by fishers, who seek them not just to supply local markets for their meat, but to meet lucrative demand for their fins from Asia.
- Sawfish and wedgefish species have now been fished to local extinction in Ghana, and marine biologist Issah Seidu warns guitarfish will be next.
- Earlier this year, Seidu was the recipient of a Whitley Award, which will support the work of his NGO alongside Ghanaian fishing communities to research and protect guitarfish.

As Australia expands seismic testing, experts warn of profound effects on sealife
- Research has shown the intense, impulsive underwater noise from marine seismic surveys can harm marine animals up and down the food chain. Yet marine scientists say major gaps remain in understanding how the effects of repeated exposure may accumulate across ecosystems over time.
- Even so, the technology is becoming embedded in Australia’s energy transition plans, as projects increasingly rely on seismic surveys not only to search for gas, but also to repeatedly monitor sites where carbon dioxide captured during gas production would be injected permanently into seabed rock formations.
- The process, known as carbon capture and storage, is relatively new, and while proponents say it is the only way to reach net zero goals, major economic and performance challenges remain.
- The expansion of carbon capture and storage could make seismic surveys a recurring feature of Australia’s net-zero ambitions.

What happened to the vessels Panama busted in 2025 for fishing in its flagship MPA?
- In January 2025, Panama’s government announced it had caught more than a dozen vessels fishing illegally inside the country’s flagship marine protected area, declaring it the largest such enforcement operation in the country’s history. Yet the government has released little information about the case over the past year and a half.
- To find out what happened, Mongabay sought information from Panamanian government agencies and reviewed government files that a local nonprofit obtained in freedom of information requests. Much of the information in this article, including about the number and nature of the vessels involved and the status of legal proceedings, hasn’t previously been reported.
- Two government agencies have issued fines against many of the vessel owners, though certain cases have been dismissed and the fines in other cases were reduced upon appeal. The status of criminal proceedings led by the public prosecutor’s office, a third government authority, isn’t known.
- The fishers involved protested the fines on multiple grounds; for one, they’ve said they weren’t in fact fishing. Meanwhile, a representative of the Panama-based nonprofit said the government hadn’t been strict enough in enforcing the MPA’s rules and hasn’t conducted the cases with full transparency. The agencies have rejected the criticisms.

How a community is helping sea turtles hatch in the Philippines
- The municipality of San Vicente in the Philippines’ Palawan is a vital nesting ground for Olive Ridley sea turtles.
- Nesting turtles and their eggs face an array of challenges. Predation by dogs is the most immediate threat, but rising sea levels, more severe storms and tourism development plans also loom large.
- To try to protect the turtles, Large Marine Vertebrates Research Institute Philippines, a Philippine-based NGO, runs a research project and works with paid patrollers to monitor and protect turtles and their nests.
- Community involvement is key to the group’s conservation efforts.

Melanesian nations announce intention to create massive ocean reserve corridor
- Solomon Islands is the latest Pacific island nation to sign on to a new network of marine protected areas (MPAs) known as the Melanesian Ocean Corridor of Reserves, or MOCOR, which was announced by Papua New Guinea, Vanuatu and Fiji at the first Melanesian Ocean Summit in May.
- Located in the southwestern Pacific, Melanesia is a hotspot for marine biodiversity and the discovery of new species.
- While large marine corridors can be more effective than isolated MPAs, researchers caution that robust management and enforcement are necessary to prevent them from becoming so-called “paper parks.”
- Details about MOCOR’s size, configuration, precise location, governance, enforcement mechanisms and community consultation processes are scarce.

Gray whales are suffering catastrophic population decline in the Pacific Ocean
Gray whales are experiencing a potentially catastrophic population decline, a sharp reversal from what had been considered a conservation success. As of July 6, 2026, there were 145 gray whale (Eschrichtius robustus) stranding deaths in the Pacific, according to National Oceanic and Atmospheric Administration (NOAA) data. The environmental non-profit Public Employees for Environmental Responsibility (PEER) […]
Invasive giant prawn spreads through protected areas in Brazil
- A study led by researchers from Brazil and Uruguay confirmed the presence of invasive prawns in several conservation areas along the Brazilian coast, including estuaries listed by UNESCO as Natural World Heritage Sites.
- Considered an opportunistic predator and highly adaptable to different marine conditions, the giant river prawn competes with native species for food and shelter, in addition to being a potential vector for diseases.
- While scientists demand concrete actions to stop the advancement of this intrusive crustacean, small-scale fishers report significant drops in their capture of native animals, warning about the impact of invasive species on their livelihoods.

The unsung biodiversity of the Mediterranean Sea needs urgent protection
The Mediterranean Sea accounts for less than 1% of the world’s ocean surface water, but it contains roughly 18% of global marine biodiversity. It is home to 150 million people along its coastline (roughly equivalent to Russia’s population). And it sequesters 17.2 million metric tons of CO2 each year. Joining the Newscast this week to […]
What will Africa’s story on ocean governance be? Interview with David Willima
- With the High Seas Treaty in force, African proposals to designate marine protected areas in international waters are taking shape.
- Maritime security expert David Willima talks about why the West African marine protected area proposal is advanced and why others still require careful coordination.
- Willima says that with the current transformation marine governance is going through, African countries need to be actively engaged in order to have a voice in global decision-making.

Can conservation change how the world sees the Strait of Hormuz? (commentary)
- If seen only as an oil corridor, the main question becomes how to keep energy moving, but this overlooks a much more important reality, that the Strait of Hormuz is biologically rich yet fragile.
- Featuring mangroves, seabird colonies, coral reefs, turtle nesting beaches and islands, it is a narrow ecological corridor through which the Persian Gulf exchanges water between the Gulf of Oman and Indian Ocean, connecting nature across borders.
- “If it is also seen as an ecological corridor, another question enters the room: how much ecological capital is the region willing to risk while trying to protect its political and economic capital?” a new op-ed asks.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

 Seeking swordfish, catching dolphins and whales: EU pushes to rein in driftnets
- Environmental groups continue to allege widespread illegal use of driftnets in the Mediterranean Sea.
- The use of driftnets — fishing nets, sometimes kilometers long, that drift with the ocean currents — is prohibited to catch large pelagic species like swordfish.
- Highlighting that current measures lack adequate definitions and enforcement provisions, the European Union presented a proposal to strengthen international restrictions on driftnet fishing at the International Commission for the Conservation of Atlantic Tunas technical meeting in June.
- Morocco, one of the countries most criticized for the use of illegal large driftnets, has emerged as a strong supporter of the proposal.

Illegal fishing takes a toll on Australia’s sea cucumbers
- Researchers blame an increase in illegal fishing for the decline of sea cucumbers in a remote Australian marine park and say many other reefs in the country have also been affected.
- The Australian government has launched an operation to crack down on illegal fishing in the country’s Northern Territory where the problem is acute, including for high-value sea cucumbers.
- But as long as the market for sea cucumbers remains strong in China and other East Asian countries, experts say, wild populations of this slow-growing animal could collapse and put the health of reef systems at risk in Australia and beyond.

‘The only possible transition is a just transition’: Interview with WEF’s Clemence Schmid
- Kenya formally launched the National Plastic Action Partnership (NPAP) in collaboration with the Global Plastic Action Partnership (GPAP), an initiative of the World Economic Forum, at the Our Ocean conference held in Mombasa.
- Plastic pollution is a pressing threat to Kenya’s marine ecosystems, fisheries and coastal livelihoods, driven by poor or non-existent waste management on land, along the coast and at sea.
- The initiative seeks to accelerate the transition to a circular plastics economy, which aims to reduce plastic pollution, valorize materials traditionally considered ‘waste’ and generate economic opportunities in the process.
- Mongabay spoke to Clemence Schmid, Director, Global Plastic Action Partnership (GPAP), on the sidelines of the Mombasa conference to understand what the collaborative effort is trying to achieve in Kenya.

Sightings off Southern Africa suggest blue and fin whales may be rebounding
Sightings of blue whales and fin whales off Southern Africa’s Atlantic coast have increased in recent years, according to a newly published study. This could signal recovery of the marine mammals after being virtually eliminated from the area by commercial whaling in the 20th century, the study authors say. Scientists estimate around 350,000 Antarctic blue […]
Sightings of humpback whales surge in Rio de Janeiro, fueling demand for whale-watching trips
RIO DE JANEIRO (AP) — Sightings of humpback whales off Rio de Janeiro’s coast are surging as they recover from decimation due to commercial whaling, prompting an acceleration in the demand for whale-watching excursions to spot the huge marine creatures during their annual migration. The species’ population has jumped from around 2,000 to around 35,000 […]
Can coastal infrastructure be engineered to harbor marine life instead of harming it?
- Living Seawalls is a global initiative that aims to make seawalls, marinas and other hard coastal structures more hospitable to marine wildlife by installing biodiversity-friendly panels, boulders and pilings.
- In 2025, Ireland’s first Living Seawalls installation was established at Kennedy Pier in the port town of Cobh, and marine life is already starting to colonize the panels.
- While researchers say the panels can help marine life colonize hardened coastlines, and stayed cooler than standard flat seawall surfaces, questions remain about their effect on seawalls’ main function of keeping waves at bay, leading scientists to suggest that design modifications may be needed.

A marine heat wave caused seabird deaths off California. El Nino could worsen the die-off
SAN DIEGO (AP) — Many seabirds are starving to death as a marine heat wave lingers off California and fish seek deeper, cooler waters. That’s according to scientists who say a persistent marine heat wave has shrunk the band of cold, nutrient-rich surface water where krill, anchovies and sardines thrive near the shore. Scientists fear […]
Aquatic animal and terrestrial meat trades now almost on par, FAO report finds
- The FAO recently released its State of World Fisheries and Aquaculture (SOFIA) report, a biennial collection of data that policymakers, scientists and civil society groups rely on.
- Global fisheries and aquaculture production, including algae as well as animal products, reached a record 235 million metric tons in 2024, with farmed aquatic animal production surpassing 100 million metric tons annually for the first time. This brings the total aquatic animal product trade close to that of terrestrial meat.
- The report, which covers around 70% of global fisheries, found that sustainably fished stocks fell by 2.1% to a new low of 62.4%.
- The report projects continued growth in aquatic animal production from both fisheries and aquaculture, but warns that achieving it sustainably and equitably will require greater investment, effective governance and continued innovation.

As Amazon oil drilling begins, scientists warn of risks to a little-known reef
- Brazilian state oil and gas company Petrobras has started drilling in the Equatorial Margin after years of political, scientific and environmental disputes over the risks posed by oil exploration at the mouth of the Amazon River.
- Researchers warn that the Amazon Reef system harbors a wealth of biodiversity and has not been widely studied, despite being close to Petrobras’s exploration block.
- Scientists disagree about the composition and extent of the Amazonian reefs, while environmentalists denounce attempts to downplay their ecological importance.
- Experts warn that an oil spill could reach mangroves, small-scale fisheries, and even neighboring countries, due to strong marine currents in the area.

A trailblazing Ugandan championing women in African fisheries: Q&A with Lovin Kobusingye
- In fishing communities along Africa’s coast, women are often the backbone of household economies. They process and sell fish, support households and pay school fees, often while facing significant economic and social challenges.
- Hotels, ports and other developments are reshaping many African coastlines. While they can bring jobs and investment, some women working in fisheries say they are also being pushed away from traditional landing sites and areas they have depended on for generations.
- At a recent gathering of marine organizations in Kenya, one woman stood before the audience to share the realities faced by women fishers, fish traders and others working across the fisheries value chain.
- Uganda’s Lovin Kobusingye knows those realities well. Having overcome numerous obstacles of her own to become a successful entrepreneur, she now advocates on behalf of millions of women working across Africa’s fisheries value chain, many of them women whose contributions to fisheries remain largely unseen and undervalued.

Asia’s shark and ray hotspots remain poorly protected, study finds
- A new regional assessment has identified 122 important shark and ray areas (ISRAs) across Asia, spanning more than 1 million square kilometers (386,102 square miles) and supporting 121 species, many of them threatened with extinction.
- Despite their ecological importance, only 5.4% of these habitats overlap with existing marine protected areas with only 2.8% falling within fully protected no-take zones, highlighting major conservation gaps.
- Sri Lanka has five identified ISRAs, home to nine species with eight of them threatened with extinction, but only Pigeon Island in the island’s east is formally protected, with most areas still functioning as active fishing grounds.
- The new study underscores an urgent need to move from mapping to management, using ISRAs to guide marine spatial planning, fisheries regulation and habitat protection ahead of global 30×30 ocean targets.

Chewing sounds can help decode an animal’s diet using AI, new study finds
- Scientists have developed an AI model that can listen to the chewing sounds of predators and identify what they are eating.
- The tool was trained with audio of whitespotted eagle rays crushing open shells of the mollusks they are preying on.
- It’s crucial to understand predator-prey interactions to figure out the resources the predator depends on and the pressure it puts on prey.

Six marine sanctuaries recognized as Blue Parks, four of them in Africa
- On June 16, the Marine Conservation Institute recognized six marine protected areas, three in Madagascar and one each in Senegal, Chile and Canada, as Blue Parks.
- The awards, announced at the Our Ocean conference in Mombasa, Kenya, recognize MPAs whose management is “durable, equitable and effective” at protecting marine life.
- Under the Kunming-Montreal Global Biodiversity Framework, countries agreed to protect 30% of the world’s land, freshwater and marine areas by 2030, but experts say that protection must be meaningful, not just symbolic.
- One of the common features of the awardees is the existence of some form of co-management with Indigenous peoples and local communities.

An island community in Thailand works to protect and revive its dugongs
Once a lush field of green, the seagrass meadows surrounding Thailand’s Koh Libong are now largely barren stretches of sand, devastating the island’s iconic dugong population, reports Mongabay’s Carolyn Cowan. Koh Libong’s seagrass meadows were once Thailand’s largest, and a critical coastal habitat that is protected nationally. Yet, between 2020 and 2024, seagrass cover in […]
Studying giant devil rays through war in Gaza: Interview with Mohammed Abu Daya
- Mohammed Abu Daya is a marine ecologist in Gaza. His research focuses on spinetail devil rays, a large-bodied species of ray that roams the Mediterranean Sea and beyond.
- Since 2013, Abu Daya has monitored the impact that local fisheries have on spinetail devil rays, which are listed as “critically endangered” on the IUCN Red List. Palestinian fishers occasionally target the rays when they stray into Gaza’s coastal water, as other fishing resources in the area have been depleted due to longstanding Israeli restrictions.
- Displaced by Israeli bombings during the war in Gaza that began in 2023, Abu Daya now lives in a tent, with limited access to basic necessities like food and drinking water, or to the internet. His university office has been destroyed, and he can no longer conduct research at sea. Yet he continues to carry out his scientific work, in the hope that it will help improve the conservation of devil rays globally.
- In 2025, at the height of the war, Abu Daya co-authored an international research paper documenting the behavior of spinetail devil rays and showing the importance of the Levantine region for the conservation of this species.

US moves to allow commercial fishing in Pacific marine protected areas
On June 11, U.S. President Donald Trump signed an executive proclamation to open additional commercial fishing grounds in remote areas of the Pacific. The proclamation says restoring access to these areas “will promote economic opportunity.” However, local groups warn it will open the door to overfishing in a crucial marine habitat and sacred cultural site.

Saudi parrotfish festival stretches scientific & traditional ecological knowledge (commentary)
- During the annual “hareed” festival in the Farasan Islands — an archipelago in the Red Sea off the coast of Saudi Arabia — hundreds of people run into the water to catch parrotfish, which aggregate there annually since time immemorial.
- Science cannot yet explain this annual phenomenon, but there are clues in traditional ecological knowledge and cultural history, a new op-ed explains.
- “Only by weaving [traditional] knowledge together with science can we begin to understand what we are trying to protect,” the author writes.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

To help combat illegal fishing, 15 countries commit to sharing fisheries data
Fifteen countries from Africa, Asia, Latin America and Europe adopted the Mombasa Declaration on June 17, 2026. Together, they committed to advance global fisheries transparency and strengthen efforts to combat illegal, unreported and unregulated (IUU) fishing. The declaration was adopted during the 11th meeting of the international Our Ocean Conference, held in Mombasa, Kenya. Africa […]
New walking shark discovered in Papua New Guinea
Researchers have described a new-to-science species of walking shark, which lives in the remote, shallow waters off southeastern Papua New Guinea. The newly named Dudgeon’s walking shark (Hemiscyllium dudgeonae) is a type of epaulette shark, a group of small sharks famous for their ability to use their fins to “walk” when stranded in tidal shallows. […]
French Polynesia expands ocean protections to 30% of its waters
The government of French Polynesia announced it is expanding the extent of ocean where extractive industries like seabed mining and industrial fishing will not be allowed. With this move, 30% of French Polynesia’s waters will now be fully protected. Last year on June 8, French Polynesia, a French overseas territory, established the Tainui Atea marine […]
Africa’s community-led marine organizations on which 30×30 depends
- More than 5,000 delegates are gathering in the Kenyan coastal city of Mombasa for a major global conference on the future of the oceans.
- At the heart of the discussions is ocean governance and the global push to meet the 30×30 target — protecting 30% of the world’s land, freshwater and oceans by 2030.
- But meeting that goal will depend not only on governments and international pledges, but also on community-led organizations doing the difficult work of conserving fragile marine ecosystems.
- Across Africa and around the world, thousands of grassroots groups are carrying out this work, often far from the spotlight, helping shape ocean conservation and blue economies that support local livelihoods. Mongabay spoke with representatives of four such organizations working across the continent from the Western Indian Ocean to Africa’s Atlantic coast.

‘Thinking how traffickers think’: Study uses AI to detect marine wildlife smuggling
- Researchers have developed what they say is the first AI algorithm dedicated to detecting trafficked dead marine wildlife from 3D X-ray images.
- The system was most effective at finding species with idiosyncratic shapes, like shark fins and seahorses, but also detected sea cucumbers with 86% accuracy.
- Interpol seized more marine specimens than reptiles, birds and primates combined in 2025, but experts say the illicit trade remains underrecognized compared to tracking of terrestrial animals and their parts.
- The effectiveness of the new approach may be limited by access to 3D X-ray machines in airports and mail pathways, and when officials try to distinguish between species in the same genus.

How a popular spaghetti dish is threatening Italy’s marine ecosystem
- In the waters off Naples, Italy, a single 75-minute raid by poachers can net nearly 1,000 sea urchins, an in-demand ingredient in a dish popular with tourists. A haul like that can deal a significant blow to the local urchin population.
- In a healthy marine ecosystem, fish like sea bream feed on urchins, keeping populations in check. When poachers decimate sea urchin colonies, commercial fish move elsewhere to find food, threatening legal fishers’ livelihoods.
- Experts say Italy’s marine protected areas are particularly vulnerable. Although they have criminal penalties to deter poachers, the surrounding waters have been completely stripped bare of urchins, making them attractive targets.
- Now, scientists are collecting data from law enforcement operations to raise awareness and drive regulatory changes.

Teeming with turtles: Cabo Verde island sees 80-fold increase in nesting loggerheads
- A new study finds an 80-fold increase in the population of loggerhead turtles nesting at three beaches in Boa Vista, Cabo Verde’s third-largest island, over 27 years.
- Globally, the loggerhead population has decreased by 47% over the past three generations, a decline largely attributed to anthropogenic pressures such as habitat loss, marine pollution, fishing bycatch, poaching and multiple climate change-driven impacts.
- The authors of this first-of-its-kind study of Cabo Verde’s nesting loggerheads attribute the remarkable local recovery to decades-long conservation efforts.

Australia establishes the first Sea Country Indigenous Protected Area
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. For the Karajarri people of Kimberley in northwestern Australia, the coastline, reefs, wetlands, beaches and desert-edge country form one estate, held through law, memory, work and obligation. That relationship now has new recognition, reports Mongabay’s John Cannon. In […]
Researchers find dramatic restoration on land and sea after island rat removal
When invasive rats are removed from islands, the ecological benefits can ripple across both land and sea more quickly than scientists expected, according to recent research. Scientists have long assumed that meaningful recovery after the predators are eradicated would take decades. However, researchers with the U.S.-based NGO Island Conservation conducted a rat-removal experiment on Ulong Island […]
To improve its floundering fisheries, Kenya boosts data collection on artisanal fleet
- In Kenya, fishers are experiencing increased competition for dwindling catches. A lack of data is stymying their decision-making about where and when to fish as well as the governments’ decision-making about how to manage fishing in the country, experts say.
- A new project aims to improve the collection of fisheries data, harmonize them and make them accessible to fishers and the government alike.
- It involves beefed-up data collection methods, the installation of trackers on fishing vessels and a centralized database and digital platform.
- The initiative is modeled around a program in Timor-Leste that began in 2016 and now serves as the country’s national fisheries monitoring system.

Four alleged wildlife traffickers arrested in Guinea, dried seahorses and shark fins seized
- Guinean authorities arrested four alleged wildlife traffickers and seized 41 kilograms of dried seahorses and 26 kilograms of shark and ray fins.
- The suspects are thought to be part of a transnational criminal network operating in West Africa involved in smuggling protected marine wildlife for more than four decades, and now face 1-5 years in prison and fines.
- The arrests were made when the accused were trying to sell seahorses to Chinese nationals in the country, who would then export them to China.
- The seizure highlights the growing role of West Africa as a source of the illegal global trade in marine species protected under CITES, the international wildlife agreement.

A year on, Australia’s biggest harmful algal bloom continues to wreak havoc
- The largest and longest-lasting harmful algal bloom in Australia’s history, which started in early 2025, has potentially affected more than 20,000 square kilometers of ocean waters and about a third of the coasts in the state of South Australia.
- The algal bloom has devastated marine ecosystems and caused significant economic losses in the local fishing, aquaculture and tourism industries.
- As officials, researchers and communities grapple with its ecological, health and social impacts, the bloom has exposed a lack of preparedness at all levels of government for responding to future HABs.

‘Slumping’ afflicted soft corals around a South Korean island in 2024. Will it return this year?
- In 2024, scientists and conservationists documented a soft coral “slumping” event along the southern coast of South Korea’s Jeju Island, which led soft corals to lose their shape, droop, and even die in vast numbers.
- The event coincided with record heat and rainfall, which has led scientists to surmise, in a new paper, that the “slumping” resulted from a combination of thermal stress and changes to salinity and water quality.
- However, further research and testing is needed to determine the actual cause, researchers say.
- Scientists and conservationists say that while widespread slumping did not occur during 2025 or so far in 2026, the “Super El Niño” predicted for later this year could impact Jeju’s soft corals in a similar way.

Whale strike risk rises as international shipping reroutes around South Africa
- In a new study, researchers analyzed the link between increased shipping traffic in South African waters and collisions between whales and ships.
- The research covers six whale species occurring in near- and offshore waters and shows significant spatial overlap between whale habitats and shipping traffic, making action urgent.
- The South African government, the International Maritime Organization and scientists are working together to develop measures aimed at reducing whale strikes.
- Currently, rerouting vessel traffic is not possible as too much data are missing to map the spatial distribution of whales that occur farther offshore.

New golf-ball sized blue octopus species now identified in the Galapagos
While on a deep-sea expedition in the Galapagos in 2015, scientists found a golf-ball sized, short-armed blue octopus. In a recent study, they confirmed that it’s new to science. The newly described octopus, named Microeledone galapagensis, was first sighted with a remotely operated vehicle (ROV) near an underwater mountain, roughly 1,773 meters (5,800 feet) below […]
Sea cucumber tissue survives for years in open water, study finds
Severed tissue from a cold-water sea cucumber can survive, heal, and even move independently for years in natural seawater, researchers recently found. Some animals have the ability to regenerate tissues and body parts. Certain lizards can regrow their tails, for example. Some sea stars and sea cucumbers, including Psolus fabricii that live in the cold […]
Pilot project in San Francisco Bay aims to help ships avoid gray whales
Starting in 2018, gray whales began regularly stopping in California’s San Francisco Bay, where they are vulnerable to ship strikes in one of the busiest ports in the United States. In response, researchers have deployed a monitoring network of thermal cameras and AI software to alert ships when whales are present in the bay to […]
Offshore wind power cables can affect sensory system of sharks and rays: studies
- A series of studies found that electromagnetic fields from offshore-wind farm cables can trigger various effects in bottom-dwelling sharks and rays depending on species and life stage.
- Experiments on small-spotted catsharks and thornback rays showed behavioral and developmental responses.
- The researchers concluded that electromagnetic fields may increase predation risk during early development by altering natural behaviors linked to predator avoidance.
- eDNA surveys detected multiple shark and ray species inside offshore wind farms, suggesting they may serve as potential refuge areas, though major knowledge gaps remain.

New records of ‘lost’ bamboo shark confirmed in Madagascar
For nearly 20 years, the blue-spotted bamboo shark, found only in Madagascar, went scientifically undetected and unrecorded. But researchers have now found four new records of the “lost” shark while surveying fishing villages and a Malagasy university’s fish collection. These recent records, and interviews with fishers, suggest the species may be more common than previously […]
Tiny ‘sesame’ sea slug discovered in Taiwan is first of its genus named in 30 years
Researchers have found a new-to-science species of a tiny sea slug with black and yellow spots resembling “scattered sesame seeds.” Measuring just three millimeters long (0.1 inches long), the researchers have named it Thecacera sesama, according to a recent study. Study lead author Ho-Yeung Chan first spotted the sea slug during a recreational dive in […]
France to send its last captive orcas to marine park, not sanctuary
- In May, the French government announced plans to send its last captive cetaceans — two orcas and 12 dolphins — to zoos and entertainment parks in Spain, sparking an outcry from animal welfare advocates.
- France had previously considered sending the marine mammals to an under-construction sanctuary in Canada, but decided to act more quickly because of deteriorating conditions at the shuttered Marineland Antibes park, where the animals are currently housed, according to a French official.
- The dolphins will be shifted to two marine parks in Valencia and Málaga, while the orcas — a mother and son — will be transported to Loro Parque, a zoo and entertainment park in Tenerife, one of Spain’s Canary Islands.
- Animal welfare organizations have criticized the decision, saying they believe the orcas will be used in Loro Parque’s marine shows and bred, which would go against France’s law banning the keeping and breeding of cetaceans for entertainment.

Shark Meat Nation
Brazil is the world’s largest consumer and importer of shark meat. But it’s not just restaurants and grocery stores — a Mongabay investigation found that the country’s government agencies have purchased thousands of tons of shark meat to serve in schools, hospitals, prisons, military bases, homeless shelters and other public institutions. The findings raise serious […]
Hidden ‘bubble cave’ may help world’s rarest seal steer clear of humans: Study
On the Greek islet of Formicula, researchers have found rare Mediterranean monk seals will take refuge in an air-filled “bubble cave,” according to a recent study. This type of hidden chamber, accessible via underwater passages, allows the seals to breathe, and possibly hide from tourists, the researchers said. Mediterranean monk seals (Monachus monachus), the world’s […]
New species of ghost pipefish named after Sesame Street character found in Australia
It’s “hairy,” bright orange or red and “exceptional” at camouflaging. Meet the hairy ghost pipefish, whose recent formal description demonstrates that even well-studied marine environments like the Great Barrier Reef still hold remarkable secrets for science. In a recent study, researchers shared the name of the ghost pipefish, Solenostomus snuffleupagus, for its “conspicuously shaggy appearance,” […]
Tracking Lucero: Scientists follow a rare Eastern Pacific leatherback sea turtle
Fewer than 1,000 leatherback sea turtles remain in the Eastern Pacific, nesting along the coastline that runs from Mexico to Ecuador. Scientists have previously fitted tracking devices to leatherbacks on other beaches across Latin America and from bycatch near Ecuador. However, they recently tagged the first nesting leatherback in Ecuador, the southern limit of the […]

Thai island community rallies to protect beloved dugongs, revive declining seagrass
- Seagrass beds around the island of Koh Libong in Thailand’s Andaman Sea have died off in recent years, part of wider nationwide declines scientists say have multiple, complex causes.
- The seagrass shortage has devastated the island’s once famed dugong population, jeopardizing tourism businesses and impacting the island community who have long protected them.
- Locals frustrated by slow government seagrass recovery plans are working with researchers and conservation groups to build citizen science skills and trial seagrass restoration techniques.
- Signs of hope are emerging, with recent surveys recording more dugongs in local waters, prompting local leaders to call for increased public awareness and enforcement of protections.

Scientists surveying the area found three times more seabed organisms and twice as many species compared to nearby unprotected waters. “What looks like […]
At world’s largest shark conference, scientists warn of a grim outlook across the board
- Hundreds of researchers and conservationists met in Colombo from May 4-8 for Sharks International, held once every four years.
- Major topics at the conference included the trade in shark and ray meat, reducing shark bycatch, and the use of new technologies in conservation.
- Participants also highlighted innovative programs that encourage community-based conservation, and grappled with the contentious topic of closing fisheries to aid recovery of threatened species.

China and Norway push to increase krill harvests around Antarctica
- In Antarctic waters, an international fishery targets krill, shrimp-like crustaceans that form massive schools and support the continent’s iconic wildlife. Krill meal and oil is used primarily in the production of aquaculture feed, followed by pet food and human dietary supplements.
- China and Norway are working to expand the Southern Ocean krill fishery, promoting a new management system for the fishery that would increase harvests while also establishing a long-sought marine protected area.
- The two countries are also continuing to support their krill fleets politically and financially, while adding vessels to increase harvest capacity.
- Meanwhile, several NGOs have recently stepped up their campaigns against krill fishing, arguing that the krill fleet competes for food with Antarctic wildlife species already struggling with climate change and reduced food availability such as emperor penguins and Antarctic fur seals that have both recently been declared endangered.

From caws to code: AI helps decrypt animal communication
- Scientists are increasingly using artificial intelligence models to decode the communications of other species.
- The Earth Species Project has built a generalizable model that could be used across species; the team also works with scientists around the world to develop custom models for specific species.
- In northern Spain, ESP’s AI tools are helping scientists understand how a population of cooperative-breeding crows communicate with one another.
- The technology is also being deployed to understand how orcas communicate with each other, and how underwater noise affects their communication.

The Southern Ocean is key to our planet’s future & we have a chance to protect it this year (commentary)
- The wildlife-rich Southern Ocean is not simply another stretch of water in need of protection: just one part of it — the Antarctic Peninsula — is home to roughly a third of the global krill population, which sustains large populations of whales, penguins, seals, seabirds, fish and more.
- The Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) is responsible for governing these waters, and the U.K. is set to chair its pivotal 45th annual meeting this year.
- This is an opportunity to act on Southern Ocean conservation, a new op-ed by former U.K. environment minister Zac Goldsmith argues, but that’s not all: “It would also send a powerful signal, at a time when multilateralism is under strain, that countries can still come together around shared values and act for the global good,” he writes.

Sawfish in Sri Lanka may be ‘functionally extinct,’ but refuges remain
The sawfish, recognizable by its distinctive saw-shaped snout or rostrum, is now thought to be “functionally extinct” in Sri Lankan waters. This, researchers say, means that while a few individuals may still exist, their numbers are likely too low to maintain a viable breeding population, reports contributor Malaka Rodrigo for Mongabay. In a 2021 study, […]
Sharks and rays do not know boundaries and a new high seas treaty seeks to protect them
- A recent panel discussion at a global conference on sharks and rays explored how the newly adopted Biodiversity Beyond National Jurisdiction (BBNJ) Agreement, or the High Seas Treaty, could transform conservation of migratory sharks known to travel across national borders into international waters.
- Speakers highlighted sharks’ vulnerability once they leave protected national waters, emphasizing how effective conservation requires international cooperation to avoid threats from industrial fishing, bycatch, and habitat degradation across geographical boundaries.
- The treaty creates a legal framework for establishing marine protected areas in the high seas, with scientists noting that Important Shark and Ray Areas (ISRAs) could help identify critical migratory routes and habitats for future protection.
- Panelists said the agreement on BBNJ marks a historic shift in ocean governance, but warned that enforcement, political cooperation and coordination with treaties such as CITES, the Convention on Migratory Species and the Convention on Biological Diversity will be essential for meaningful shark conservation.

Arabian Gulf’s fragile marine ecosystem threatened by current crisis (commentary)
- During the Iran–Iraq war of the 1980s and subsequent conflicts, large-scale oil spills and fires caused lasting environmental damage in the Arabian Gulf.
- A new commentary by United Arab Emirates special envoy of the minister of foreign affairs for nature Razan Khalifa Al Mubarak explains that recovery of impacted marine ecosystems, where it occurred, took decades, but that this progress is now threatened by the new conflict along the gulf.
- “What is at stake today is not only the repetition of past damage, but its amplification across interconnected systems,” she writes in arguing for an end to the current conflict.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

A baby boom for North Atlantic right whales, but extinction still a threat
Calving season for the critically endangered North Atlantic right whale has come to a close with 23 new baby whales, the most calves born in a single year since 2009. Part of the baby boom during the winter calving season can be attributed to females giving birth at closer intervals than in years past: 18 […]
In Senegal, artisanal fishing kills a surprising number of sharks and rays: study
- A study at two fish landing sites in southern Senegal found artisanal fisheries catch large numbers of sharks, rays and guitarfish, most of them threatened species.
- The authors suggest artisanal fishing may have a greater impact on these species than industrial trawling due to its large scale and limited monitoring and enforcement.
- Much of Senegal’s trade in artisanally caught sharks and rays is poorly monitored and exports take place without required permits, raising concerns about ongoing species population declines in the region, experts say.

A 10-year whale shark satellite study helps create new protected area in Indonesia
- Fishers and scientists joined together in Indonesia for a 10-year study to protect whale sharks (Rhincodon typus).
- The bagan fishers’ unique relationship with the endangered whale sharks enabled scientists to satellite tag the fish.
- The data from the decade-long study revealed previously unknown migration routes, feeding grounds and a whale shark nursery.
- The data will be used to help create a marine protected area designed for whale sharks.

Iceland plans to resume whale hunting this summer
Icelandic commercial whaling company Hvalur hf. plans to resume whale hunting this summer, following a two-year pause in commercial operations. In 2024, the Icelandic government issued the company a five-year license allowing it to catch up to 209 fin whales (Balaenoptera physalus) annually. However, Hvalur hf. didn’t hunt any whales in 2024 or 2025. Iceland’s […]
Endangered whale protections may be delayed to 2035 under Trump-backed plan
PORTLAND, Maine (AP) — For roughly 380 right whales left in the North Atlantic, which can die after getting tangled in fishing ropes or hit by ships, the Trump administration said this month it wants to delay new protections by almost a decade in favor of commercial fishing interests. The sleek black whales, which weigh as much as a […]
Tierney Thys, marine biologist and interpreter of the sunfish
- Tierney Thys spent decades studying the giant ocean sunfish, using its improbable form to ask broader questions about life in the open ocean.
- Trained as a marine biologist, she moved between research, filmmaking, and public storytelling, helping make complex ecological processes accessible to wider audiences.
- In later years, her work extended beyond the sea, linking issues such as textiles and microplastics back to ocean health.
- Across her career, she returned to a central concern: how people come to value the natural world, and what sustains that commitment over time.

World’s largest shark conference is set to begin in Sri Lanka next week
- When Colombo hosts Sharks International 2026 from May 4-8, it will be the first time a global shark and ray science conference is convened in Asia, drawing global attention to the region’s fisheries and biodiversity challenges.
- The conference will bring together leading global experts, policymakers and fisheries managers to strengthen the links between science, policy and practice, particularly in regions where shark fisheries are both economically important and ecologically under pressure.
- Key discussions will revolve around methods to bridge persistent gaps between shark conservation policy and on-the-water reality, and how regulations exist in formal frameworks but fail to translate into consistent awareness and action, compliance and enforcement.
- More than one-third of shark and ray species are now threatened with extinction globally, driven by overfishing, bycatch and international demand, making improved fisheries governance and enforcement a central focus of the 2026 meeting.

Global trade in sea cucumbers ‘alarming’ with many species at risk: Study
- The global trade in sea cucumbers has grown since 2013 and continues to decimate the populations of many species, according to a recent study that cites “escalating impacts” and calls for stronger conservation measures.
- The study found that global capture of sea cucumbers increased from 2013 to the late 2010s and dipped slightly during the peak pandemic years of 2020 and 2021, the last years in the study period.
- China and it’s special administrative region of Hong Kong, where sea cucumbers are used in traditional medicine and consumed as a delicacy on special occasions, are the main importers as measured by dollar value, the study found.

One of the world’s largest deep-sea coral reefs discovered off Argentina
- Scientists have discovered what may be one of the world’s largest cold-water coral reef systems, located about 1,000 meters (3,300 feet) deep in Argentina’s territorial waters, with much of it remaining unmapped.
- The reef, dominated by the rare coral species Bathelia candida, hosts a surprisingly rich ecosystem, including dozens of deep-sea species new to science.
- Researchers found signs of human impact, including fishing debris and possible trawling damage, and worry the reef area might also be targeted for oil and gas exploration.
- The researchers are testing restoration techniques, including the installation of 3D-printed “artificial corals,” which they hope will encourage the rapid growth of new corals.

AI tool listens for endangered orcas in real time to reduce human disturbance
- An AI initiative is listening to southern resident orcas in real-time to help them steer clear of vessels and noisy coastal construction.
- OrcaHello builds on a network of underwater microphones to detect orcas and push out alerts that have helped pause coastal construction and redirect boat traffic as the orcas pass by.
- Southern resident orcas are considered an endangered subspecies, with only 76 remaining individuals.
- Major threats to the species include a decline in their food sources, primarily Chinook salmon, along with noise pollution and vessel traffic.

A campaign to protect one of the planet’s only expanding kelp forests takes shape
- Stretching more than 1,300 kilometers (800 miles) along the coast of South Africa, the Great African Seaforest is home to thousands of species, many of them endemic, and is one of the few expanding kelp forests in the world.
- The Academy Award-winning documentary “My Octopus Teacher” was set in the Great African Seaforest.
- Although slivers of the kelp forest fall under marine protected areas, the ecosystem is mostly not conserved.
- Marine scientists are working to inventory the species found here in the hopes of raising its profile, both internationally and among the communities that live alongside it on the South African coast.

Translucent microsnail discovered in Cambodia: Photo of the week

Drones aid dugong conservation as threats mount across their range
- Drone technology is revealing new information about the elusive dugong, a marine herbivore classified as globally vulnerable but already extinct in parts of its range.
- Scientists are using drones to improve estimates of dugong numbers and conduct noninvasive health checks.
- Dugongs feed exclusively on seagrass meadows, where their foraging helps to maintain these important carbon sinks.
- Researchers are highlighting the need to link efforts to conserve seagrass meadows with protecting dugongs.

San Francisco Bay emerges as high-risk area for migrating gray whales
Gray whales have one of the longest known migrations of any mammal — from the Arctic near Alaska, to the lagoons of Baja Mexico, where they mate and give birth. This annual migration, longer than 19,000 kilometers (12,000 miles), has been altered by climate change, with profound consequences for the 15-meter (50-foot) mammals. Since 2016, […]
Invasive ferrets removed from an island in a world-first
Rathlin Island off the north of Northern Ireland is now free from feral ferrets that were harming its native seabirds. Conservationists say this is the first time these nonnative animals, which were domesticated from polecats some 2,000 years ago, have been completely eradicated from any island. Ferrets (Mustela furo) were introduced to Rathlin in the […]
Deep-sea wildernesses are more important than the promise of seafloor mining (analysis)
- A scientist who was part of a major 2008 expedition exploring the promise of deep-sea mining writes in a new analysis that what they found offshore of Papua New Guinea ended his enthusiasm for the nascent industry.
- The biodiversity documented by their remotely operated vehicle — added to the fragility and uniqueness of the geology and ecology they documented — was clearly too special to perhaps permanently decimate for electric vehicles and renewable energy.
- “I entered this project in good faith, working with the mining company to help determine whether or not deep-sea mining at Solwara I could be conducted with minimal harm to the marine environment. I exited convinced that there is no viable path forward for hydrothermal vent mining, anywhere in the ocean.”

Council recommends opening US Pacific marine monuments to commercial fishing
A U.S. fishing regulator recently recommended allowing commercial fishing across all four of the country’s Pacific marine national monuments. The Western Pacific Regional Fishery Management Council (Wespac) said the move is “about restoring sustainable fishing.” Conservationists and native peoples, however, say it will damage some of Earth’s most pristine ocean ecosystems. The monuments — Pacific […]
Half of seabirds are declining. Protecting marine flyways could help save them
- Nearly half of migratory seabird species are in decline, in part because conservation systems stop at borders while the birds do not.
- A new study maps six “marine flyways” spanning the world’s oceans, showing how 151 species depend on connected routes across dozens of countries.
- These pathways link breeding sites, feeding areas, and migration corridors, but face persistent threats from bycatch, invasive species, and climate change.
- Coordinating protection along these routes—rather than focusing only on isolated sites—could improve conservation outcomes for seabirds at a global scale.

Migratory species summit adopts new marine protections amid extinction warnings
- Delegates to the latest meeting of the Convention on Migratory Species of Wild Animals adopted new protections for 40 migratory species, including 33 marine animals like sharks, seabirds and shorebirds.
- The convention’s 15th Conference of the Parties (COP15), held in Brazil March 23-29, recognized the importance of “marine flyways” for migratory birds and highlighted key marine biodiversity areas.
- It also urged protection of seamounts from destructive fishing practices and a precautionary approach on deep-sea mining to address potential impacts on migratory species.
- Conservation advocates lauded the steps taken at COP15, but the summit also issued stark warnings that extinction and species decline are accelerating.

Latin America’s largest hospital complex cancels plan to buy shark meat
- Last month saw a series of new policy developments for sharks in Brazil.
- Brazil’s biggest hospital complex said it would strike shark meat from a planned 2026 procurement, though the boneless fish could still be served at some of its institutes.
- The environment agency issued a host of new rules, including a ban on shark fins detached from the carcass, drawing ire from industry groups.
- A court ruled that federal procurements of shark meat for public institutions must meet new species labeling and traceability requirements.

Is the Galápagos damselfish extinct?
- A once-common reef fish in the Galápagos has not been seen since 1983, raising the question of whether it has already disappeared.
- A recent study by Jack Stein Grove and colleagues concludes the species is likely extinct, based on decades of failed searches and historical records.
- Its disappearance is linked to the severe 1982–83 El Niño, which disrupted the islands’ nutrient cycles and food webs.
- The case highlights how even well-known marine ecosystems can lose species quietly, with declines only becoming clear in hindsight.

Orcas never seen before in Seattle delight whale watchers with a visit
Seattle (AP) — When tourists travel to Seattle, it’s common to take in the Space Needle and the downtown skyline from Puget Sound. It’s an itinerary that a newly arrived pod of killer whales appears to be following too. Three orcas that had not previously been recorded in the Seattle area have delighted whale watchers with several […]
Talks to reduce funding for overfishing remain stalled at WTO meeting
- Delegates at a recent World Trade Organization summit in Cameroon agreed to continue “Fish Two” negotiations aimed at a deal to curb government subsidies that support unsustainable fishing, but progress remains limited, with just three countries blocking consensus despite broad support.
- The first phase of the deal, “Fish One,” entered into force in September 2025 and now has 116 ratifications; but key fishing nations, including India and Indonesia, have not joined.
- Disputes over Fish Two center on fairness: Developing countries argue the draft text disadvantages them, particularly through sustainability-based exemptions that favor wealthier nations with better scientific capacity.
- A four-year “sunset clause” triggered by Fish One’s entry into force now puts pressure on talks: If a full agreement is not reached by 2029, the entire deal, including Fish One, risks collapsing.

A ‘big book’ documenting Cameroon’s sharks & rays fills critical conservation gap
- Between 2015 and 2023, researchers working with fishers recorded more than 7,000 sharks and rays caught at sea and landed along Cameroon’s coast.
- The recorded animals represent 45 species, of which 13 are critically endangered.
- Their research found that most sharks and rays landed in Cameroon’s fisheries are juveniles, raising serious concerns about population recovery.
- The data help scientists better understand species composition, catch trends and conservation priorities along Cameroon’s coast.

Baby octopus in Argentina: Photo of the week
These eggs belong to a small octopus known in Argentinian Patagonia as pulperos. The Patagonian octopus (Octopus tehuelchus) is one of the more common octopus species in the region, but researchers still haven’t been able to determine its global conservation status, although reported catches in Patagonia have declined over the past 50 years. The photo […]
Singapore resort said to halt controversial dolphin sourcing, breeding
- Singapore’s Resorts World Sentosa is to end sourcing dolphins from the wild and has suspended a captive breeding program, according to sources.
- The company is assembling a team of experts to decide the future of more than 20 Indo-Pacific bottlenose dolphins, most of which were captured from the Solomon Islands in 2008 and 2009.
- The resort has maintained the dolphins are well cared for and the exhibit at Singapore’s Oceanarium serves educational and conservation purposes.
- Experts say that rehabilitation and release of the dolphins is possible, with transfer to a natural sea pen the first step for assessment.

A stranded whale in Germany’s Baltic Sea weakens as hopes of its return to the Atlantic fade
A stranded humpback whale in Germany’s Baltic Sea looks weaker, and experts fear it won’t be able to find its way back to the Atlantic despite several attempts at its rescue this week. A 500-meter (yards) restricted area was enforced around the whale so it could get some rest and hopefully free itself, officials said Sunday in a […]
Traditional protection proves more successful for clams in American Samoa
- A study found that on the most populated island in American Samoa, traditional village-based protections and remote sites had the highest density of giant clams — outperforming federally designated no-take zones in one case.
- The authors suggest that traditional community stewardship could offer a viable alternative to federal restrictions, especially in areas communities rely on for giant clam harvesting, while respecting traditional management practices.
- The giant clams, which are slow-growing, face threats from habitat degradation, ocean warming, watershed pollution and overharvesting.
- The NOAA National Fisheries Service proposed protections for several giant clam species in 2024 which could lead to a top-down ban on harvesting. Some sources say a blanket ban without including communities in conservation strategies would impact people who rely on harvesting.

Investigation of permit violations in South Africa’s shark fishery pending
- In June 2025, South African authorities fined a shark fishing vessel caught violating its permit conditions.
- It is not the first time the country’s small shark fishery has made headlines, including for breaches of conditions by fishing in protected areas and illegally cutting heads and fins off of its catch, preventing effective monitoring.
- In October, the fisheries department said it would consider further action; no updates have been made public, but satellite data suggest the Zanette has fished inside a marine protected areas on at least four occasions since then.

New strategy to reverse Kenya’s shark decline tries to bring fishers on board
- A new strategy by government agencies, scientists and coastal community members proposes a working plan of 19 goals to reverse the steep decline of sharks and rays in Kenya.
- As small-scale fishers have a lot of influence on the marine species’ populations, most of the goals directly involve fishers or try to get them on board to make the conservation strategy a success.
- Goals include alternative fishing gear, different livelihoods to reduce fishing pressure, increasing the number of locally managed marine areas, involvement of fishers in conservation decision-making and more effective enforcement.
- Community fishing representatives say they are on board with the plan but highlight that a few points, like concrete and viable alternative livelihoods and fishing methods, need to be offered to reach the conservation goals.

Small ray of hope for Sri Lanka’s sawfish, now feared ‘functionally extinct’
- Known for its saw-shaped snout or rostrum, the sawfish is now feared “functionally extinct” in Sri Lankan waters, with the last record dating back to 2017.
- Three critically endangered sawfish have historically been reported in Sri Lanka — the narrow sawfish (Anoxypristis cuspidata), largetooth sawfish (Pristis pristis), and green sawfish (P. zijsron) — but they are listed as either endangered or critically endangered due to overfishing, habitat loss and bycatch.
- Researchers say small populations may still be surviving and call for more surveys to identify potential habitats toward conservation.
- The sawfish’s rostrum serves as both a weapon and a sensory organ, helping it to hunt prey in murky waters, and in Sri Lanka, these are traditionally offered to churches as a sign of goodwill.

Family and friends help sperm whale mother and newborn during birth
With the notable exception of humans, most mammals give birth alone. But in July 2023, researchers in the Caribbean witnessed something extraordinary: sperm whales not only attending a birth but actively helping both mother and newborn. Some of the whales present were not even related to the mother, known as Rounder. “Kinship barriers dissolved,” notes […]
The squid rush in the South Pacific is forcing regulators to act
A recent annual meeting of the fisheries regulator for the South Pacific tackled a familiar challenge: how to manage one of the world’s largest squid fisheries before mounting pressure turns it into a depleted one. The meeting produced some new safeguards, though much of the hard work still lies ahead, reports Francesco De Augustinis. The […]
On Manatee Appreciation Day, remember these gentle giants who protect aquatic ecosystems (commentary)
- Slow-moving, peaceful and curious, manatees quietly maintain the health and balance of aquatic ecosystems, from rivers to bays and coasts worldwide.
- Manatee Appreciation Day is observed annually on the last Wednesday of March, and it’s a good time to remember why these animals matter, and the people who have dedicated their lives to protecting them.
- “The gentle giants of our oceans have survived for millions of years. Whether they survive the next century depends on all of us,” a new op-ed argues.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

Brazil protects huge coastal area with endangered dolphins and megafauna fossils
Brazil’s federal government created a huge conservation area on March 6 to protect a critical biodiversity hotspot in the Atlantic Ocean. The newly created Albardão marine park and coastal environmental protected area are home to at least 25 endangered species and Pleistocene epoch megafauna fossils. The new national park is off the coast of Brazil’s […]
Pharmaceutical companies move away from horseshoe crab biomedical testing
Horseshoe crabs were crawling along the shallow sandy bottoms of Earth’s oceans 200 million years before the first dinosaurs came on the scene. But some populations have declined dramatically with the rise of humans, raising concerns they may be headed toward extinction. One of the biggest drivers of their population collapse is their unsustainable harvest […]
Outlook for migratory species worsens amid habitat loss & avian flu, report finds
- A U.N.-backed report finds that nearly half of the world’s migratory species protected under a global treaty are now decreasing — and about one in four now faces extinction.
- Habitat loss and degradation as well as hunting and fishing are driving these declines, but a deadly virus, Highly Pathogenic Avian Influenza, is also taking a heavy toll on bird populations.
- Wildlife corridors and protected ocean networks can play a pivotal role in conserving imperiled species: Animals need to move to find food, a mate and migrate.

Marine biologist Edie Widder chases bioluminescence in new ‘Life Illuminated’ film
- The new documentary “A Life Illuminated” traces the career arc of U.S. marine biologist Edie Widder, an expert on bioluminescence who’s made headlines for decades.
- The film documents her team’s attempt to capture a remarkable deep-water phenomenon called “flashback” on camera. (Spoiler alert.)
- Bioluminescence serves a variety of functions for deep-sea creatures, and flashback may originate from bioluminescent bacteria on drifting organic matter, Widder said.
- “A Life Illuminated” will make its Washington, D.C., premiere on Mar. 19, the first night of the D.C. Environmental Film Festival, where Mongabay is a media partner.

Modest controls put on freewheeling squid fleet at South Pacific fisheries meeting
- The 14th meeting of the South Pacific Regional Fisheries Management Organisation (SPRFMO) took place in Panama City from March 2-6.
- The intergovernmental organization regulates fishing activities in the high seas of the South Pacific, a vast area encompassing about 59 million square kilometers.
- Key decisions concerned tightening regulation of the jumbo flying squid fishery following increased fishing activity and signals of overfishing, and adopting measures to reduce illegal fishing practices and labor abuses in the squid fleet.
- Decision-makers also took steps toward finalizing a new management procedure for jack mackerel. Negotiations over regulating bottom trawling, a source of disagreement at recent SPRFMO meetings, remained stalled.

Bangladesh sees rise in ray, shark fishing as traditional seafood species dwindle
- Bangladesh has seen a sudden rise in illegal shark and ray fishing and consumption in recent years.
- A decrease in catch of traditionally consumed fish species and the lower prices of sharks and stingrays have led to this rise in popularity. Additionally, traders export ray skins and shark parts to East and Southeast Asian countries.
- Sharks and rays are protected species in Bangladesh and existing laws prohibit their catching, selling and consumption.
- Conservationists blame the weak law enforcement and lack of awareness among fishers and suggest that the government initiate stricter conservation measures besides providing subsidies to the poor fishers.

Belugas facing euthanasia at shuttered Canada theme park may find new homes in US
- In August 2025, Canada’s only entertainment park with cetaceans, Marineland of Canada, closed for good, prompting concern about the fate of 30 beluga whales and four dolphins remaining at the facility.
- After a plan to transfer them to a theme park in China was blocked by the Canadian government, Marineland called for euthanizing the animals. The Canadian government has now conditionally approved their possible transfer to four U.S. institutions.
- Keeping highly intelligent and social creatures in concrete-lined tanks adversely affects their health and well-being, experts say.
- With changing public perceptions and a growing number of countries, including Canada, banning the keeping and breeding of whales and dolphins, conservationists are calling for alternatives to house the more than 3,700 cetaceans in captivity worldwide, including building seaside sanctuaries.

Plastic, from home and abroad, spills into Türkiye’s waters
- Türkiye has become a major destination for plastic waste recycling, notably from Europe and the U.K. Most of this scrap heads to the roughly 180 waste facilities handling plastic in Adana province.
- But large quantities are dumped along riverbanks or escape the facilities through their wastewater and eventually flow downstream into the Mediterranean Sea.
- The resulting pollution is taking a toll on riverine and marine ecosystems, including important sea turtle nesting sites.
- Some experts say Türkiye should stop importing plastic altogether to stem the tide of pollution, but the government has said the recycling industry plays an important economic role.

25 years after ‘disaster’ declaration, major U.S. fishery makes a comeback
- In 2000, the U.S. commerce secretary declared the groundfish fishery on the U.S. West Coast a “disaster,” with 10 key species overfished to below a quarter of their healthy levels.
- Fisheries authorities empowered by federal conservation laws took drastic action: They cut off vast tracts of the ocean to trawling, slashed fishing quotas and bought fishing vessels to remove them from operation. Many fishers were thrown into painful retirement.
- Careful management and innovation in the intervening years has led to a remarkable turnaround: In October 2025, fishery officials declared the last of the 10 overfished species to be rebuilt, years earlier than expected, and fishers have catches they thought would never be possible again.
- Even so, fishers’ profits have been low, and experts worry that key conservation programs could lose their teeth to cost-cutting measures and deregulation.

Seafood fraud is rampant, imperiling fish populations, report finds
- Up to roughly 20% of aquatic products are intentionally mislabeled as the wrong species or otherwise fraudulent, posing environmental and health risks, according to a new report.
- Inaccurate representation of species is one of the most frequent forms of fraud, the report says.
- Other cons include misrepresenting place of origin or eco-certification status, and adulterating a product to affect its weight or appearance of freshness.
- The report calls for governments and industry stakeholders to establish better traceability systems, use advanced detection methods, and educate the public. An NGO expert says government action on traceability is key.

Proposed shark net near Club Med resort in South Africa sparks conservation clash
- A proposal by municipal authorities in South Africa’s KwaZulu-Natal province to install shark nets at a public beach has triggered a public debate about the need to install gear that’s highly lethal to sharks and other marine life, and raised questions about its legality.
- The proposal, which authorities say will protect beachgoers from shark attacks, was made in anticipation of increased visitor numbers to Tinley Manor Beach once a new Club Med resort opens in the area later this year.
- Some scientists and environmentalists argue that shark nets and drum lines are outdated as they cull and kill nontarget species indiscriminately, including those protected under South African law.
- South Africa’s Department of Forestry, Fisheries and the Environment said it’s considering whether installing the net should trigger an environmental impact assessment. Some experts also question the legality of existing nets.

China’s Pacific squid fishery rife with labor, fishing abuses: Report
- A new report from U.K.-based NGO the Environmental Justice Foundation draws on interviews with 81 fishers, mainly Indonesian sailors who worked between 2021 and 2025 on 60 Chinese vessels targeting jumbo flying squid (Dosidicus gigas) in the Southeast Pacific Ocean.
- It documents frequent labor abuses affecting crew members, including several indicators of forced labor as described by the International Labour Organization.
- The report also documents regular shark finning, targeted hunting of marine mammals, and involvement in suspected illegal fishing incidents, often inside Ecuador, Peru or Chile’s exclusive economic zones.
- The report was launched days before the annual meeting of the commission of the South Pacific Regional Fishery Management Organisation, the intergovernmental body that manages the fishery. Officials with fishing organizations mentioned in the report and members of China’s delegation to the meeting did not respond to Mongabay’s request for comment on the report.

Avian flu strikes California’s northern elephant seals; area quarantined
- Experts confirmed that seven young northern elephant seals on the beach at California’s Año Nuevo State Park carried a deadly form of avian influenza, H5N1, the first recorded infection in these seals.
- This highly contagious virus has circulated the globe since 2020. The U.N. estimates that as of December 2025, H5N1 had infected some 598 bird species and 102 mammal species. In 2022-23, the virus devastated seal colonies off South American coastlines, sparking increased surveillance of North American marine mammals.
- This northern elephant seal population has been carefully studied for about 60 years. With close monitoring, researchers quickly discovered that sick pups were infected with Highly Pathogenic Avian Influenza H5N1.
- Since this avian flu strain emerged, there have been 131 human infections globally, including 71 in the U.S. As a precaution, California officials have banned visitors from the elephant seal beaches and canceled guided tours.

Mongabay shark meat exposé wins national journalism education award in Brazil
- On Feb. 24, Mongabay won first place in the higher education category of Brazil’s National Association of Directors of Federal Higher Education Institutions (Andifes), a top journalism education award in the country, with an investigation that revealed Brazilian state-run institutions were bulk-buying shark meat for public schools, hospitals and prisons.
- “The work stands out for its expert input from specialists and researchers, who contribute to the analysis of the environmental, health and regulatory impacts of the issue,” Andifes said in the announcement.
- In collaboration with the Pulitzer Center, the investigation published in July 2025 tracked 1,012 public tenders issued by Brazilian authorities since 2004 for the procurement of more than 5,400 metric tons of shark meat, worth at least 112 million reais.
- In December 2025, the investigation won second place in the national category of the 67th ARI/Banrisul Journalism Award, one of Brazil’s most prestigious journalism prizes.

Panama NGOs face lawsuits, asset seizures in fight over port construction
- Two environmental groups fighting the Puerto Barú project in Panama have been named in lawsuits claiming they defamed the developers and created public confusion about the project.
- The Center for Environmental Advocacy of Panama and the Adopt a Panama Rainforest Association (Adopta Bosque) say the port could damage mangroves and harm vulnerable shark and ray species.
- Both organizations have had their assets seized, including bank accounts and properties that serve as private nature reserves.

Azores dodges proposal to overturn no-fishing zones in its giant new MPA network
- A law establishing the Azores Marine Protected Areas Network was approved in October 2024 and took effect recently, on Jan. 1 this year.
- The network now safeguards 30% of Azorean waters, 287,000 square kilometers of seascape sheltering a rich array of marine life, and makes up the largest MPA network in the North Atlantic Ocean.
- Not two weeks later, on Jan. 15, the Azores Parliament voted on a measure that upholds a core provision of the MPA network, after it came under fire in recent months: No fishing inside the fully protected areas, which constitute half the vast network.
- Conservationists expressed satisfaction, broadly, with the agreement, but fishers’ groups expressed disappointment.

It’s electric: Scientists develop cheap way to keep sharks off fishing hooks
- Unintentional catch is a major reason that more than a hundred shark species are threatened with extinction.
- A new study found that creating a small electric field around fishing hooks using zinc and graphite is enough to keep many sharks away.
- Researchers have for decades tried to take advantage of sharks’ electrosensitivity to develop devices to keep them off fishing hooks. The authors of the new study chose zinc and graphite because they’re nonmagnetic, cheap and readily available materials.
- The lead author and two former students are pursuing commercial applications for the new method.

Southern elephant seals recover in Southern Africa, but global picture is mixed
- The southern elephant seal’s conservation status in South Africa has improved from near threatened to least concern, with experts citing four decades without major threats to its breeding colonies on Marion and Prince Edward islands.
- About 5,500 seals are estimated across the two islands, with nearly 1,400 pups recorded in 2023; strong legal protections and marine protected area status have supported recovery.
- Scientists caution that the causes of a sharp population decline in the late 20th century remain poorly understood, with possible links to food availability, climate change and oceanographic shifts.
- While South Africa’s population is recovering, other southern elephant seal populations face threats, including a devastating bird flu outbreak in Argentina, prompting debate about the species’ global conservation status.

Texas sea turtles have lost a conservation hero (commentary)
- A dedicated sea turtle conservationist on the Texas Gulf Coast has passed away.
- Carole Allen — the founder of HEART (Help Endangered Animals Ridley Turtles)— passed away this month at the age of 90.
- “Some of Carole’s accomplishments are documented in Edward Humes’ 2009 book “Eco Barons” and the 2011 PBS documentary “The Heartbreak Turtle.” But her true legacy lives on in the countless children and adults she inspired over generations,” a new op-ed says.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

In Kenya’s Jomvu Creek, women help restore a vanishing coast through crab farming
- On the outskirts of the coastal Kenyan city of Mombasa, a women’s organization in Jomvu Creek aims to transform livelihoods and the environment through mud crab farming.
- A blue economy grant is allowing the women to establish a crab-fattening enterprise and build a boardwalk through the creek, with hopes of boosting ecotourism.
- In a good month, the women’s crab sales amount to $310, meaningful income in an area where many had said they were living hand to mouth.
- Beyond income, the Jomvu women see themselves as caretakers of the creek, linking crab farming to mangrove restoration and planting nearly 1 million seedlings; the trees stabilize the shoreline, reduce erosion and create nursery habitats for fish and crabs.

Brazil’s Rio de Janeiro bans shark meat in most state schools
The Brazilian state of Rio de Janeiro recently announced it has banned the purchase of shark meat for roughly 95% of its state-run schools, citing environmental and health concerns. A July 2025 Mongabay investigation found shark meat was commonly purchased for use across Brazil in public institutions, including eldercare facilities and schools. The exposé found […]
Abandoned tuna-fishing devices pollute the Galápagos Marine Reserve
- The tuna industry commonly uses fish aggregating devices (FADs) to efficiently collect large volumes of fish; when these devices are lost or abandoned, they can harm marine wildlife and habitats.
- In Ecuador, lost FADs can drift into the Galápagos Marine Reserve, a protected area with hundreds of endemic and threatened species, where they pollute the environment with plastic, harm reefs and entangle wildlife.
- Local agencies and organizations are developing ways to prevent FADs from entering the marine reserve in the first place and trying to clean up the mess they make when they do get in.

Critical shark and ray habitats in Western Indian Ocean largely unprotected: Study
- Almost half of the Western Indian Ocean’s shark and ray populations are considered threatened with extinction, as populations decline.
- The Important Shark and Ray Areas (ISRAs) project has mapped out 125 areas across the Western Indian Ocean that are critical for the survival of many species.
- Yet only 7.1% of these ISRAs fall within existing marine protected areas, and just 1.2% are in fully protected areas where fishing is prohibited.
- Researchers identified challenges related to fishing pressure as the most significant threat to sharks and rays in the region.

Whale sharks released from nets along India’s coast as fishers turn rescuers
- Once hunted and butchered for oil and meat, whale sharks (Rhincodon typus) are now being rescued by fishers along India’s western Arabian Sea coast.
- Since 2001, the nonprofit Wildlife Trust of India has been educating fishing communities about whale sharks, training fishers in safe disentanglement techniques and offering compensation for destroyed nets.
- During that time, more than a thousand whale sharks have been released from accidental entanglement in fishing nets along India’s west coast.
- However, experts say the compensation for rescues remains insufficient and that social security, insurance, training and livelihood-linked incentives should be offered to protect the fishers who engage in whale shark rescues.

New global map shows where sharks and rays most need protection
- A new report delineates 816 areas of the ocean that should be protected to help shark and ray populations recover following decades of overfishing.
- The areas, each of which hosts key activities such as reproduction for at least one threatened shark or ray species, are visible on an online atlas open to the public.
- The ISRAs don’t take up all that much of the ocean’s surface: less than 3% for the nine regions where research has been completed, which shows how achievable conservation of sharks and rays is, the lead author said.
- The report was released ahead of a major meeting of the parties of the Convention on the Conservation of Migratory Species (CMS), a United Nations treaty, in Brazil in March, where area-based management decisions for marine species are on the agenda.

Rio de Janeiro state bans shark meat for school meals
- The government of Brazil’s Rio de Janeiro state has banned shark meat for meals in most of the schools it manages, after pressure from conservationists and school meal advisers raising health and environmental concerns.
- The shark meat ban applies to all 1,200 schools run by the state education department, but not to the thousands of other schools in the state that are managed by municipalities and private entities.
- A Mongabay investigation in July 2025 revealed 1,012 public tenders issued since 2004 to procure more than 5,400 metric tons of shark meat in 10 of Brazil’s 26 states, including Rio de Janeiro.
- Industry groups have criticized the Rio de Janeiro government’s decision, dismissing health risks linked to shark meat consumption, and complained of a lack of transparency in the decision-making process, noting that the ban has yet to be published in the state’s official gazette.

Coast-to-coast coral assessment reveals Thailand’s reefs losing complexity
- Marine scientists have documented Thailand’s coral reefs in unprecedented detail, providing a crucial baseline against which reef managers can measure future change.
- The surveys indicate that, as in other parts of the world, Thailand’s reefs are losing structural complexity, becoming dominated by simpler boulder-forming corals, while staghorn and branching species die out.
- Experts say the new baseline can help steer future strategies to prepare for future bleaching events through reef restoration and assisted reproduction.
- The surveys were conducted just before the full effects of the 2024 global bleaching event were felt in Thai waters, which will have inevitably taken an as-yet-unquantified toll on the region’s reefs.

More than 5 years after Wakashio oil spill, questions linger in Mauritius
- In 2020, amid the chaos of the pandemic, the island nation of Mauritius was hit by one of the worst environmental disasters in its history when the MV Wakashio, owned by Nagashiki Shipping, crashed into the coral reef barrier off the southeastern part of the island.
- The ship spilled around 1,000 metric tons of oil into the waters near three sites of ecological importance; more than five years on, conservationists and fishers say the Mauritian government quietly allowed the entire episode to fade from public memory, with little scrutiny.
- When Mongabay visited mangroves in 2025 that had been affected by the oil spill, fuel oil still lingered in the water-soaked earth; it could persist for decades, experts warn.
- Vikash Tatayah at the Mauritian Wildlife Foundation facilitated the evacuation of animals considered at risk due to the oil spill, including lesser night geckos, to the U.K.; eggs from the geckos and their descendants were returned to Mauritius in 2025.

Greenland sharks retain functional vision despite extreme longevity
Greenland sharks are the longest-living vertebrate known to science, topping out at more than 400 years old, and scientists have largely believed they were nearly blind. But new research suggests they actually can see, and, remarkably, maintain their vision for more than a century. Greenland sharks (Somniosus microcephalus) mostly live in the cold waters of […]
Study tracks fishing boats to see how heat waves affect fish distribution
- A new study suggests an early way to detect ecological shifts during marine heat waves: Use fishing vessel tracking data.
- The study found that tracking data could provide early detection of extreme northward and inshore shifts in albacore tuna and Pacific bluefin tuna distribution in response to heat waves and showed when such shifts weren’t happening despite high sea surface temperatures.
- The authors position fishers as “apex predators” and build on research that finds that predators are good ecosystem sentinels.

South Africa’s great white shark population worries researchers
Great white shark populations in South Africa are disappearing, driven largely by human activities that are likely responsible for the collapse of a locally critical apex predator. That’s the conclusion of a review paper published by a group of scientists and conservationists who analyzed data on the abundance of great whites in South African waters. […]
North Atlantic right whale births increase
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. Scientists monitoring North Atlantic right whales have recorded an increase in births this winter. Fifteen calves have been identified so far, an encouraging figure for a population that has struggled to sustain itself. There were an estimated 384 […]
Mauritania’s fishmeal fever ends as government tightens regulation
- Until recently, Mauritania was a major fishmeal producer, home to the world’s second-highest number of processing plants, with the boom driven largely by lax regulations and the rapid issuance of permits between 2007 and 2021.
- By 2021, more than half of Mauritania’s total pelagic fish catches were being used for fishmeal.
- That same year, however, the government began introducing stricter regulations and strengthening enforcement of rules governing the sector.
- Only eight fishmeal plants in Mauritania remain active as of September 2025, according to Mongabay’s estimates, and fishmeal production has fallen by more than half since its peak in 2020.

From ‘extinct’ to growing, a rare snail returns to the wild in Australia
Rarely do species presumed extinct reappear with renewed hope for a better future. But researchers in Australia not only discovered a wild population of Campbell’s keeled glass-snail on Australia’s Norfolk Island in 2020 — they’ve now bred the snail in captivity and recently released more than 300 individuals back into the wild, where they’re multiplying. […]
Declared extinct in 2025: A look back at some of the species we lost
Some species officially bid us farewell this year. They may have long been gone, but following more recent assessments, they’re now formally categorized as extinct on the IUCN Red List, considered the global authority on species’ conservation status. We may never see another individual of these species ever again. Or will we? Slender-billed curlew This […]

Mongabay shark meat investigation wins national journalism award in Brazil
- A Mongabay investigation that revealed Brazilian state-run institutions bulk-buying shark meat for public schools, hospitals and prisons won second place in the ARI/Banrisul Journalism Award, one of Brazil’s most prestigious journalism prizes.
- In collaboration with the Pulitzer Center, Mongabay revealed how authorities had issued 1,012 public tenders since 2004 for the procurement of more than 5,400 metric tons of shark meat, raising environmental and public health concerns.
- In a statement, the Rio Grande do Sul Press Association (ARI) said the award “recognized the talents” in professional and university categories amid a record number of entries, up 40% from the 2024 edition.
- Following the revelations, the investigation sparked several impacts, from a call for a public hearing in Brazil’s lower house of Congress, a citation in a lawsuit to ban shark meat from federal procurements, to an industry debate questioning the harms of shark meat consumption.

Century-old corals reveal the Pacific Northwest is acidifying faster than expected
- When compared with historical samples, corals show that the Salish Sea and California Current System are acidifying faster than anticipated because of greenhouse gas emissions. Models indicate that at this rate, carbon dioxide levels in the oceans will continue rising faster than concentrations in the atmosphere.
- Increasingly acidic seas pose growing risks to sensitive marine life, from clams and oysters to any organism with a spine, as well as economically important fisheries and the communities that depend on them.
- British marine ecologist Stephen Widdicombe calls the threat existential. Our continued failure to cut emissions can only lead to “a world where uncontrolled climate change including ocean acidification leaves us with an ocean that is less productive, less diverse and less able to provide humans with the wealth of services that we currently all benefit from,” he said.

Bethany “Bee” Smith, researcher who documented a megamouth shark alive, died in a diving accident, aged 24
- Bethany “Bee” Smith was part of a generation of scientists who worked in the field while also explaining their work publicly, narrowing the distance between research and spectacle without denying the risks that came with it.
- Trained as a marine biologist, she spent years studying sharks, working with fishing communities and researchers, and focusing on conservation problems where trust and policy mattered as much as data.
- After years of preparation and failed attempts, she achieved a rare feat: documenting a live megamouth shark, one of the least understood large animals on Earth, in work focused on evidence rather than thrill.
- She died at 24 during a freediving accident in Indonesia while working on a shark conservation project, after reaching a goal that had occupied years of careful effort and preparation.

Zombie urchins & the Blob: California sea otters face new threats & ecosystem shifts
- Southern sea otters living along California’s coast are struggling in warmer seas, with new threats and changing food sources. They, like the other two sea otter subspecies, are classified as endangered.
- Human disturbance, especially in Monterey Bay, is limiting the otters’ ability to forage, impacting mother and pup survival. Meanwhile, sharks are expanding their range as waters warm, with increasing attacks on otters.
- Following a mass die-off of the purple sea urchin’s predators — sunflower and ochre sea stars — the urchins decimated kelp forests, which are important sea otter habitat. Mussels then proliferated, replacing urchins in the otter’s diet, and invasive green crabs are now also on the menu.
- Otter numbers seem to be dropping, but a definitive census has not been conducted since 2019. A new population estimate based on data and statistical modeling is due to be released soon.

Drug gangs in Ecuador and Peru also involved in shark fin trafficking: Report
Narcotrafficking gangs operating out of Manabí, a coastal province of Ecuador, are also involved in trafficking shark fins alongside their drug operations, according to a recent investigation by Ecuadorian news agency Código Vidrio. Evidence from wiretaps, surveillance and raids seen by Código Vidrio reporters suggests that gangs are capturing and finning sharks and transporting the […]
The lab-in-a-backpack busting illegal shark fins: Interview with Diego Cardeñosa
- Diego Cardeñosa chose lab-based DNA research over fieldwork during his Ph.D. on sharks, betting it could deliver greater conservation impact despite being less glamorous.
- He developed a portable, rapid DNA test — like the kits used during the COVID-19 pandemic — that allows inspectors to identify shark species from fins on the spot, solving a key bottleneck that let illegal shipments slip through.
- The tool has evolved from identifying a handful of protected species to distinguishing among more than 80 sharks and rays in a single test.
- Now deployed across multiple countries, the relatively low-cost kit is expanding through grant support, with plans to adapt the technology to other trafficked wildlife beyond sharks.

A rare right whale spotted off Ireland resurfaces near Boston
In a rare sighting, a critically endangered North Atlantic right whale, first photographed in 2024 off the coast of Ireland, was recently reidentified near Boston, U.S., on Nov. 19. This is the first time a North Atlantic right whale (Eubalaena glacialis) was initially documented in Irish waters; before that, it was unknown to scientists. The […]
Brazilian government serves shark to infants, prisoners and more: How Mongabay broke the story
Mongabay senior editor Philip Jacobson joins Mongabay’s podcast to discuss a two-part investigation published this year in collaboration with the Pulitzer Center about how state governments in Brazil have been procuring shark meat — which is high in mercury and arsenic — served to potentially millions of schoolchildren and thousands of public institutions. With Mongabay’s […]
Elephant seals can recognize the voices of their rivals
Elephant seals spend most of their lives at sea, returning to shore just twice every year to molt and breed. The breeding season typically includes males weighing thousands of kilograms violently clashing with each other to compete for females. New research finds the hefty mammals remember the voices of rivals they’ve met before and retreat […]
Global manta and devil ray deaths far exceed earlier estimates: Study
- A new global assessment estimates more than 259,000 manta and devil rays (genus Mobula) die in fisheries each year, far exceeding previous figures, with researchers warning that the true toll is likely higher due to major data gaps.
- Small-scale fisheries account for 87% of global mortality, with India, Indonesia, Sri Lanka, Myanmar and Peru responsible for most mobulid deaths .
- The study documents steep, long-term declines, including in Mozambique, the Philippines and the eastern Pacific Ocean. Yet many losses came to light only recently due to late adoption of monitoring and weak reporting.
- Researchers say the recent uplisting of all mobulid species to CITES Appendix I, which bans international commercial trade, is a key step, but note that national-level protections, improved data reporting, gear reforms, and better spatial management are needed to reduce mortality.

Unregulated tourism risks disrupting Timor-Leste’s whale migration
- 2025 has been a big whale tourism season in Timor-Leste; operators were fully booked during the peak season of September to December.
- But increasingly aggressive practices fueled by competition between tour operators could mean “another Sri Lanka,” where whales already stressed by climate-induced food scarcity are disappearing from the area.
- East Timorese are mostly excluded from the sector, which is controlled by expats and foreign tour operators raking in thousands from “bucket listers” and social media “influencers.”
- Whale tourism in Timor-Leste needs regulation, enforcement and legal compliance to ensure sustainable, inclusive growth, experts say.

The last of the Vaquita Porpoise (cartoon)
With an estimated less than 10 individuals alive, the vaquita porpoise of the Gulf of California is on the brink of extinction. Entanglement in gill nets used for fishing totoaba fish in the Sea of Cortez has been the prime threat to vaquitas, and while bans are already in place, the lack of enforcement leaves […]
‘Myopic’ fisheries managers toy with a new ‘tragedy of the commons’ (commentary)
- There are many examples of “tragedies of the commons,” whether in the atmosphere as a result of carbon dioxide pollution, or in the oceans because of marine plastics. But arguably the largest in the world is caused by overfishing, a new op-ed argues.
- The general absence of effective fisheries regulations that ensure the conservation of healthy fish populations endangers whole oceans and the billions of people who depend upon fish for their livelihoods.
- “Currently, fisheries ministers are myopically obsessed with the pain the industry always claims it would suffer next year if the right conservation policies were adopted. They should look instead at how long we have been getting it wrong, and how quickly things could be turned round,” a new op-ed argues.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

South Africa withdraws abalone listing even as illegal trade threatens species
- Ahead of the recent CITES summit to hash out wildlife trade regulations, South Africa was expected to table a proposal that would have tightened the legal trade in South African abalone, a shellfish in high demand in East Asia.
- The proposal was aimed at protecting an endangered species that’s been severely depleted by a massive illegal trade driven largely by organized crime.
- However, the South African delegation withdrew the proposal at the last minute, amid ongoing tensions in the country between conservationists, abalone farmers and coastal communities dependent on income from the illegal trade.
- A recent report by wildlife trade NGO TRAFFIC calls for coordinated international action to curb the illegal trade, including a CITES listing.

A rare bright spot for whales: Decades of conservation pay off for endangered population in Canada
- Northern bottlenose whale populations have struggled to rebound, even though commercial whaling was outlawed in their habitats more than 50 years ago.
- Long-term monitoring shows that one population of the species has begun to recover since their year-round habitat, a submarine canyon off Canada’s east coast known as the Gully, became a Marine Protected Area in 2004.
- The Gully MPA provides a rare marine conservation success story, but protection for marine mammals that migrate is more complex.

Countries back strong new trade limits for sharks and rays at CITES summit
Delegates at a global summit to update international wildlife trade rules have agreed on sweeping new protections for more than 70 shark and ray species. The move marks a significant step toward effectively tightening the legal trade in some of the world’s most threatened marine life. The meeting in Samarkand, Uzbekistan, running through this week, […]
45 more shark species up for CITES protections; tight vote expected
- Twenty-nine houndsharks and 16 gulper sharks are up for listing on CITES Appendix II at the wildlife trade regulator’s summit in Uzbekistan this week.
- Conservationists expect the vote to be close, with critics saying “lookalike” species shouldn’t face trade restrictions. Proponents argue it’s necessary given the lack of knowledge among customs officials.
- Houndsharks are widely consumed for their meat in Europe and Australia, while gulpers are hunted for their liver oil.

Chronic diseases prevalent across animals, but understudied: Study
From obesity in cats and dogs and osteoarthritis in pigs, to cancer in whales and high blood glucose in racoons, chronic diseases are increasingly becoming a concern across the animal world, a recent study finds. Most of these ailments can be traced back to human-driven changes, the author says. Antonia Mataragka, the study’s author from […]
Abrolhos: A South Atlantic marine treasure in need of protection
- Located off the coast of the Brazilian states of Bahia and Espírito Santo, the vast Abrolhos Seascape is home to some of the South Atlantic Ocean’s richest marine biodiversity. Here, more than 500 species inhabit coral reefs, mangrove forests and islands. Brazil’s largest humpback whale breeding ground also occurs within the seascape.
- Yet little legislation has been created to protect this region, leaving it at risk of predatory fishing and deep-sea mining: Less than 2% of the South Atlantic’s largest coral reef, which occupies 46,000 square kilometers within the wider Abrolhos Seascape, is fully protected.
- A recent study identified critical areas and vulnerable ecosystems within Abrolhos Seascape that the authors say need urgent conservation action; these include rhodolith beds — clusters of limestone rock that are crucial for climate security and marine species reproduction.

‘Forever chemical’ contamination could undermine sea otters’ fragile recovery in Canada
- Sea otters living along the coastline of Canada’s British Columbia province are exposed — and absorb — forever chemicals, a new study shows.
- Each of the 11 sea otters tested carried residues PFAS chemicals, with concentrations higher for those living near dense human populations or shipping lanes.
- The Canadian government released an assessment earlier this year recommending that PFAS be classed as toxic and is moving toward adopting tighter rules for these chemicals. Environmentalists support the initiative.

For sharks on the brink of extinction, CITES Appendix II isn’t protective enough (commentary)
- Listing shark species under CITES Appendix II, which allows for well-monitored sustainable trade, has helped to save some sharks from extinction. But some species are so threatened that they need to be listed on Appendix I, which bans all trade.
- New research has revealed that many fins belonging to sharks protected by Appendix II are still being sold in large numbers in Hong Kong, one of the biggest markets, supporting the need for action on Appendix I listings for some species at the CITES COP20 meeting that commences next week in the Uzbek city of Samarkand.
- “Governments meeting at COP20 in Uzbekistan should follow the science, support these proposals, and help save these sharks and rays from the brink of extinction. It’s the only way to give these species a fighting chance at survival,” a new op-ed argues.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

Wolf hauls up crab trap to eat bait, hinting at possible tool use
Researchers in Canada have documented a wild gray wolf hauling a crab trap out of the water to eat the bait inside, according to a recent study. Researchers suggest it may be the first recorded example of possible tool use by a wolf (Canis lupus). The finding emerged from a program maintained by Indigenous Haíɫzaqv […]
Lethal dose of plastic for seabirds and marine animals ‘much smaller than expected’
- A new study looking at the impacts of plastic ingestion by seabirds, sea turtles and marine mammals found that relatively small amounts of consumed plastic can be deadly.
- The research analyzed the necropsy results for more than 10,000 animals and quantified the amount of plastic that could prove deadly as well as the types of plastic with the biggest impact, which included synthetic rubber, soft plastics (such as plastic bags and wrappers) and discarded plastic fishing gear.
- Overall, one in five of the deceased animals had consumed plastic (affecting 50% of all studied sea turtles, 35% of seabirds and 12% of marine mammals); nearly half of the species studied were considered threatened or near threatened on the IUCN Red List.
- The researchers didn’t consider other health impacts of plastic, such as chemical exposure and entanglement, which led the lead author to conclude the study likely underestimates the “existential threat that plastic pollution poses to ocean wildlife.”

Offshore fossil fuel exploration jeopardizes Brazil’s climate leadership, study says
- Ahead of the COP30 U.N. climate summit in Brazil, a report by environment-monitoring organization SkyTruth mapped the environmental impact of the advance of offshore exploration for fossil fuels in Brazil, criticizing the country’s unfulfilled energy transition promises.
- The study detected 179 probable oil slicks in Brazilian waters since 2017, as the oil and gas sectors boomed. Analyses showed that traffic from fossil-industry vessels grew by 81% between 2012 and 2023, while methane burning skyrocketed — releasing into the atmosphere the equivalent emissions of 6.9 million cars annually.
- According to the investigation, Brazil still embraces environmentally controversial initiatives, such as oil exploration at the mouth of the Amazon River. This agenda brings risks to rich marine ecosystems and Indigenous and traditional communities, moving the country further away from its climate and conservation goals.

Trade in marine fish for aquariums includes threatened species, lacks oversight: Study
- A new study of major U.S.-based online retailers of marine fish bound for aquariums found that nearly 90% of traded species are sourced exclusively from the wild, including a number of threatened species, and that the trade is poorly tracked.
- The study raises concerns about the ecological impact of the trade on marine ecosystems, including around coral reefs, in countries such as Indonesia and the Philippines, where the fish are caught.
- Experts called for more work to develop sustainable fisheries and aquaculture in coastal communities in the Global South, and for building consumer awareness and establishing eco-certification schemes.

Study maps whale shark stranding hotspots in Indonesia, highlights conservation needs
- A new study has identified whale shark stranding hotspots in Indonesia and linked them to seasonal ocean conditions, offering scientists a clearer picture of when and where risks are highest.
- The researchers found that most strandings involved juveniles and often occurred during upwelling seasons; they highlighted that human pressures such as fishing gear, ship traffic and pollution may further increase the danger.
- The study calls for stronger rescue networks, better community training, and international cooperation to improve survival rates and protect these migratory animals across the region.

Pakistan declares its third marine protected area, but has a long way to go
- In September, Pakistan declared its third marine protected area, around Miani Hor Lagoon on the country’s central coast.
- The biodiversity-rich lagoon hosts a lush mangrove forest, numerous bird species and threatened marine mammals.
- Conservationists welcomed the new marine protected area as a baby step toward meeting the country’s so-called 30×30 commitment to protect 30% of its land and sea by 2030. However, the new addition puts Pakistan’s total protected marine area at just 0.23% of its marine and coastal jurisdiction.
- The scope of protections for the new protected area remains to be determined. Local people expressed concern that restrictions could upend the livelihoods of the local community, which depends on the lagoon and mangroves and already lacks basic necessities.

Sea anemones and hermit crabs form a mutualistic relationship in Japan
Japanese researchers have described a new species of sea anemone that appears to share a mutually beneficial relationship with hermit crabs. The pale pink sea anemones, now named Paracalliactis tsukisome, were found attached to the shells of hermit crabs (Oncopagurus monstrosus). The researchers described the anemone based on 36 specimens that fishing trawlers collected between […]
Mongabay launches dedicated Oceans Desk to expand global reporting on marine ecosystems
- Mongabay has launched a dedicated Oceans Desk composed of a global team of journalists specialized in reporting on oceans, fisheries and marine conservation.
- The desk, which includes editors, reporters and program directors from across Mongabay’s newsroom, marks a strategic shift to deepen our coverage of marine ecosystems.
- Mongabay’s ocean reporting has already led to real-world impacts, including exposing corruption in Chilean marine protected area management and informing international sanctions on a Chinese fishing company related to illegal shark finning and abusive labor practices.
- The Oceans Desk marks a milestone in Mongabay’s growth over more than two decades and strengthens the organization’s ability to inform, inspire and sustain effective action on marine conservation worldwide.

Expedition charts Cook Islands seafloor, amid scrutiny over mining motives
- Between Oct. 1 and 21, a U.S government-funded vessel, the E/V Nautilus, conducted an expedition in the Cook Islands’ exclusive economic zone (EEZ), following an agreement between the U.S. and the Cook Islands to “advance scientific research and the responsible development of seabed mineral resources.”
- During the 21-day expedition, the E/V Nautilus mapped more than 14,000 square kilometers (5,400 square miles) of the Cook Islands’ seafloor while also documenting deep-sea biodiversity.
- Environmental activists protested the expedition, arguing it would help accelerate deep-sea mining in the Cook Islands. The crew of the E/V Nautilus, however, rejects the accusation.
- The Cook Islands government has issued three deep-sea mining exploration licenses, which will expire in 2027. One company operating in the Cook Islands has said it hopes to apply for an exploitation license in 2027.

Antarctic conservation summit closes with stalemate on MPAs & krill fishing rules
- The annual meeting of the international body responsible for the conservation of Southern Ocean marine ecosystems concluded Friday with no progress on two contentious issues before it: the creation of new marine protected areas and the strengthening of regulations governing the fishery for krill (Euphausia superba), a species on which numerous iconic species of Antarctic wildlife depend.
- This year’s annual meeting of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) was particularly tense, due to a clash between two occasionally overlapping groups of countries: on one side, those working to establish new marine protected areas (MPAs), and on the other, those more focused on increasing krill fishing.
- CCAMLR has considered proposals to establish three large MPAs annually for years but has failed to pass them under its consensus-based decision-making process. This year was the same, due to vetoes of MPA proposals by Russia and China.
- The combination of a lack of will to reinstate previously agreed regulations governing the krill fishery and a new push to drastically increase the krill harvest suggests a change in direction at CCAMLR toward more permissive fishing.

Chaos on Cambodia’s Coast
Along Cambodia’s rapidly transforming coastline, illegal trawling, elite-backed development, and weak enforcement are driving marine ecosystems and fishing communities to the brink. This 2024 series investigates the institutional breakdown behind the country’s marine crisis, from ineffective patrols in protected areas to billion-dollar land deals displacing small-scale fishers. It examines the competing interests reshaping Cambodia’s coast, […]
Night dives reveal hidden alliances between young fish and larval anemones
- A new study, drawing on nighttime underwater photography, documented previously unknown “symbiotic associations” between juvenile fish and larval anemones, with some fish staying close to the anemones, and others carrying them around.
- The study suggests the fish may gain protection from predators by associating with the toxic anemones, while the anemones could benefit from being transported by the fish to new parts of the ocean.
- An outside expert also proposed that anemones might receive additional benefits, such as nutrients from the fish’s excretions or from food scraps left behind.
- All of the experts emphasized that more research is needed to fully understand the dynamics of these relationships.

Norway’s proposal to double krill harvests raises tension at Antarctic conservation summit
- Norway has proposed almost doubling the catch limit for krill in the Southern Ocean, a proposal that has exacerbated tensions at the annual meeting of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) in Australia. Conservationists have expressed concern because the continent’s iconic wildlife depend on krill for sustenance.
- The CEO of Aker BioMarine, a Norwegian company that dominates the Southern Ocean krill catch, said it has been working with CCAMLR member countries to advance the proposal as well as create a marine protected area around the Antarctic Peninsula.
- Chinese and Russian delegates have voted for years to veto new marine protected areas in the Southern Ocean.
- Russia came into the spotlight at this year’s meeting following its arrest of Leonid Pshenychnov, a researcher at the Ukrainian Institute of Fisheries, Marine Ecology and Oceanography and a longtime member of the Ukrainian delegation to CCAMLR.

On first International Day of the Deep Seabed, we seek stewardship and consensus (commentary)
- “I could not be more delighted to celebrate this inaugural International Day of the Deep Seabed,” writes the secretary-general of the International Seabed Authority (ISA) in a new op-ed at Mongabay.
- On Nov. 1, 2025, she notes that the world will for the first time mark a day that celebrates the great biodiversity of the planet’s mysterious deep seabed and its potential role in the future of humanity’s progress, while reiterating that consensus-building among member states and nongovernmental actors remains critical to ensure its stewardship.
- “Together, by delivering on our commitments under the Law of the Sea, we can ensure that this last great frontier remains a source of wonder, discovery, opportunity and shared benefit for all humankind,” she argues.

In Mauritius, an NGO is tracking the sex life of corals to save them
- Mauritius will soon be home to one of the largest projects in the Western Indian Ocean aimed at restoring corals through sexual propagation.
- The scientific research for the Odysseo coral restoration initiative is led by U.S.-based nonprofit Secore, which has also worked in the Caribbean Sea and reported success in breeding heat-tolerant corals.
- The initiative aligns with a recent policy push by the Mauritian government to promote coral restoration through sexual propagation as opposed to through asexual methods.
- However, this method of coral restoration is in its nascency in this region, and Secore is currently focused on gathering knowledge that will help it choose species to breed, donor sites to collect sperm and egg cells, and transplanting sites for newly grown coral.

Report finds dangerous mercury levels, highlights mislabeling in shark meat sold in EU
- Nearly a third of shark meat samples taken from products sold in Europe contained dangerously high methylmercury levels, with all tope shark and almost a quarter of blue shark samples exceeding EU safety limits, a new study finds.
- Much shark meat is mislabeled under names like rock salmon, huss or veau de mer, leaving consumers unaware they’re eating shark and could be ingesting a potent neurotoxin.
- Methylmercury can’t be cooked out, builds up in human tissue and can cause lasting neurological harm. Meanwhile, shark populations are declining, threatening marine ecosystem stability.
- The study’s authors urge stricter labeling laws, tighter food monitoring and consumer education, arguing that eating apex predators is both ecologically and medically unsustainable.

Two years later, no closure for family of missing Ghanaian fisheries observer
- Samuel Abayateye, a father of two, tasked with monitoring a Ghana-flagged tuna-fishing vessel, was reported missing on Oct. 30, 2023.
- Two years on, his family still hasn’t receive any formal updates from the Ghanaian police or any other agency about what happened to Abayateye.
- The authorities haven’t shared the results of a DNA test on a body found a few weeks after Abayateye went missing, which the family believe was his.
- Mongabay made repeated attempts to contact the police, but didn’t receive a response about the case.

Australia celebrates ‘humpback comeback,’ but a main food source is under threat
News of Australia’s “humpback comeback” is making waves globally. Numbers of humpback whales (Megaptera novaeangliae) on the nation’s east coast have rebounded to an estimated 50,000 from a historic low of just a few hundred before commercial whaling was outlawed in the 1970s. And wildlife scientist and whale expert Vanessa Pirotta joins the podcast to […]
Mexico adopts protections for Atlantic sharks
Mexico recently adopted national regulations protecting several threatened shark species in the Atlantic from being caught or retained as bycatch. Shark conservationists welcome the protections but say they are long overdue, coming years after the country’s commitments to a multilateral fishery regulator. Mexican fisheries catch a significant number of various shark species in the Atlantic […]
Nickel mining damage near UNESCO site stirs outrage in southern Philippines
- A recent survey by the Davao Oriental provincial government engineering office revealed that a strip mine operating in the province had scraped bare about 200 hectares of forestland.
- After the survey, the provincial governor said the province would order the Pujada nickel mine to cease operations.
- The mine is within 10 kilometers of two protected areas: the Mount Hamiguitan Range Wildlife Sanctuary, a UNESCO World Heritage Site; and the Pujada Bay, a nationally protected seascape.

Arctic seals edge closer to extinction as sea ice vanishes
- Three Arctic seal species have been moved up to higher threat categories on the IUCN Red List, with one now endangered and two now near threatened.
- Global warming is melting away the sea ice they need for breeding, resting and feeding, which has led to widespread breeding failures among ice-dependent seals.
- Loss of sea ice is also opening the region to more human activity, including shipping and oil exploration, bringing added disturbance, noise and pollution.
- The IUCN warns a similar pattern is emerging in the Antarctic. It says urgent global emissions cuts, along with stronger local protections such as reducing bycatch and pollution, are needed to prevent further declines.

Booming sea otters and fading shellfish spark values clash in Alaska
- In Alaska, a state brimming with iconic wildlife — from grizzly bears to king salmon, humpback whales to harbor seals — the charismatic, densely coated sea otter stands out as perhaps the state’s most hotly debated, controversial species.
- Sea otters were nearly hunted into extinction a century ago for their luxurious pelts. But they have been surging in population in the Gulf of Alaska, bringing both benefits to nearshore ecosystems and drawbacks to the shellfish economy (due to the otters’ voracious caloric needs).
- Described by commercial shellfish harvesters and Native Alaskans as pillagers of clams and crabs, sea otters are seen by many marine biologists as having positive impacts on kelp forests — important for biodiversity and carbon storage. Scientists stress that shellfish declines are complex, with sea otters being just one among multiple causes.
- Native Alaskans are the only people given free rein to hunt sea otters. But long-standing federal regulations stipulating who qualifies as Native Alaskan make it illegal for most to manage their own waters. Tribes are fighting for regulatory changes that would enable them to hunt and help balance booming sea otter populations.

Rare dugong calf sighting in Alor spotlights seagrass & marine mammal conservation
- A rare sighting of a dugong calf in Alor, Indonesia, has renewed focus on the health of the region’s seagrass ecosystem and the species’ fragile future.
- Conservationists say the presence of multiple dugongs indicates a thriving habitat, but threats from tourism, habitat loss and limited population data remain pressing concerns.
- Authorities and experts are pushing for stronger monitoring and coordinated conservation strategies under a forthcoming national action plan.

South African sharks threatened by fisheries, weak enforcement
- The only permit holder in South Africa’s demersal shark longline fishery has been reported breaching permit regulations, raising questions about the sustainability of the fishery.
- The fishery targets critically endangered and endangered shark species with no catch limits in place to prevent overfishing.
- Target species are already depleted, according to scientific assessments, while little is known about bycatch of other protected and endangered species.

Mining the deep-sea could further threaten endangered sharks and rays
- A new study indicates that deep-sea mining could threaten at least 30 species of sharks, rays and chimaeras, many of which are already at risk of extinction.
- The authors found that seabed sediment plumes and midwater discharges of wastewater from mining activities could cause a range of impacts on shark, ray and chimaera species, including, but not limited to, disruptions to breeding and foraging, alterations in vertical migration, and exposure to metal contamination.
- The authors recommend precautionary measures, including improved baseline monitoring, the development of protected zones, and discharging wastewater below below 2,000 m (about 6,600 ft).
- With companies planning to begin deep-sea mining in international waters as early as 2027, the authors say more research is urgently needed to understand the full ecological impact of this emerging industry on biodiversity.

Green turtle rebounds, moving from ‘endangered’ to ‘least concern’
The green turtle, found across the world’s oceans, is recovering after decades of decline, according to the latest IUCN Red List assessment. The species has been reclassified from endangered to least concern. “I am delighted,” Brendan Godley, a turtle expert from the University of Exeter, U.K., told Mongabay. “It underlines that marine conservation can work, […]
Indonesia falls short in bid to increase its share of southern bluefin tuna catch
- The Commission for the Conservation of Southern Bluefin Tuna (CCSBT), a multilateral body that manages the stock of southern bluefin tuna, held its annual meeting Oct. 6-9 in Bali, Indonesia.
- Indonesia pushed for a larger share of the global catch, which is currently dominated by Australia and Japan, but CCSBT members instead kept each nation’s share unchanged.
- Members also agreed to once again fully fund a key stock monitoring program, and to set up a future meeting for discussion of seabird protection in the fishery, amid criticism from conservationists that the commission hasn’t done enough to protect seabirds.

Abandoning Antarctic krill management measure threatens conservation progress (commentary)
- Until 2024, spatial limits across four sub-areas of the Antarctic Peninsula region had reduced the risk of concentrated fishing in areas preferred by whales, seals and penguins.
- The Convention for the Conservation of Antarctic Marine Living Resources (CCAMLR) had taken an ecosystem-based approach, recognizing that effects of fishing can ripple through ecosystems; but with the recent lapse of its Conservation Measure 51-07, ships can now concentrate their fishing efforts in key wildlife foraging hotspots.
- This October, as delegates gather to discuss CCAMLR priorities, the authors of a new commentary argue that, “At stake is more than a fishing rule, but also the commitment to manage fisheries proactively, rather than reactively.”
- This post is a commentary. The views expressed are those of the authors, not necessarily of Mongabay.

First oarfish sighting in Sri Lanka highlights citizen science in marine protection
- Scientists have documented the first-ever record of an oarfish (Regalecus russellii) in Sri Lanka, a 2.6-meter (8.5-foot) specimen caught off the country’s western coast.
- The find expands the known distribution of oarfish into the Indian Ocean, offering a new baseline for studying this rarely seen deep-sea species.
- Meanwhile, another oarfish was recorded in India’s Tamil Nadu this year, while within 20 days, three oarfish have been recorded from Australia and New Zealand, puzzling naturalists.
- The importance of promoting citizen science and raising awareness among fishers is needed.

Will California’s marine mammal conservation success come undone?
- With protection, many of California’s marine mammals — including whales, sea lions and seals — have made remarkable recoveries over the last half-century since bipartisan passage of the U.S. Marine Mammal Protection Act.
- However, climate-linked changes have now pushed the gray whale population into a state of collapse.
- Despite comebacks, marine mammals face a plethora of threats from pathogens, pollutants — including oil and plastic — disappearing food and more.
- In California, people and institutions are fighting for marine mammals and ocean biodiversity, but federal protections could be substantially weakened if proposed amendments to the Act move ahead.

Octopus farming is a dangerous detour for marine conservation (commentary)
- Proponents of octopus farming claim it can reduce fishing pressure on wild octopus populations by supplying the seafood industry, and even suggest that these efforts could contribute to restocking wild populations in the future.
- In reality, they have a poor feed conversion rate, requiring a large amount of wild-caught marine protein to produce a relatively small amount of octopus, which risks exacerbating, rather than easing, pressure on wild fish populations and marine ecosystems that depend on them, the author of a new op-ed argues.
- “Octopus farming is a dead end masquerading as a solution. It does not address the root causes of wild population declines — it compounds them. The global community must resist the temptation to exploit another wild species under the guise of sustainability,” the author writes.
- This post is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

Marine life are thriving on Nazi missile debris in the Baltic Sea: Study
As Germany demilitarized after World War II, it dumped massive amounts of its leftover munitions into the Baltic Sea. A recent study has found that some of those submerged weapons, which are still releasing toxic compounds, now host more marine organisms than the sediments around them. In October 2024, researchers used a remotely operated vehicle […]
From South America to Asia, seahorses vanish into trafficking pipeline
- In June 2025, Ecuadorian police seized a package containing almost 3,000 seahorses that were likely destined for Colombia.
- Most seahorses are caught in industrial and artisanal trawl nets as bycatch, but they are then funneled into a lucrative illegal trade.
- Researchers have identified the busiest trafficking routes: Peru to China, Hong Kong and Vietnam.
- Seahorses are in high demand for use in traditional Chinese medicine, and are also sold as trinkets and as exotic additions to aquariums.

Study spotlights West Papua habitat as whale sharks face increased pressures
- A new study shows the Bird’s Head Seascape in West Papua is a crucial nursery for juvenile whale sharks, where most sightings involved young males feeding around fishing platforms.
- Researchers documented 268 individuals over 13 years, with more than half showing injuries tied to human activity, raising concerns about fisheries, tourism and emerging mining pressures.
- Scientists warn that protecting these habitats with stricter rules and better management is essential for the survival and recovery of the endangered species.

Long-lost white shark tag traces remarkable journey from South Africa to SE Asia
- The discovery of a satellite tag from a subadult female white shark in Indonesia marks the first recorded connectivity of white shark movement between South Africa and Southeast Asia.
- The white sharks found in South Africa and Australia belong to different genetic pools, which makes the two populations distinct from one another, even though they share the same migratory route.
- The biggest threats facing white sharks in South Africa and Indonesia are unsustainable fishing, where the sharks become both the bycatch and main catch.
- While there are attempts to support local fishers to pioneer shark conservation instead of hunting them, such efforts are thwarted by lack of funding.

How we probed a maze of websites to tally Brazilian government shark meat orders
- A recent Mongabay investigation found widespread government purchases of shark meat in Brazil to serve in thousands of public institutions.
- The series has generated public debate, with a lawmaker calling for a parliamentary hearing to discuss the findings.
- Here, Mongabay’s Philip Jacobson and the Pulitzer Center’s Kuang Keng Kuek Ser explain how we built a database of shark meat procurements.

‘Super big deal’: High seas treaty reaches enough ratifications to become law
- The agreement on marine biodiversity of areas beyond national jurisdiction, also known as the high seas treaty, was reached in 2023 with much fanfare in marine conservation circles, partly because it sets up a system for establishing marine protected areas (MPAs) in international waters.
- On Sept. 19, Morocco became the 60th country to ratify the deal, which means it will become binding international law in January 2026.
- Experts and advocates celebrated the milestone, calling it a win for conservation and international cooperation.
- Uncertainty remains in how the treaty will interact with other regulatory regimes for fishing and mining, among other activities.

Mongabay shark investigation cited in motion to ban Brazil fin exports
Brazil’s top environment council cited a recent Mongabay investigation as it weighed a ban on shark fin exports and the use of wire leaders, a type of industrial fishing gear, within marine protected areas, Mongabay staff writer Karla Mendes reported. Brazil’s National Environmental Council, known as CONAMA, voted in favor of recommending a ban for […]
Iberian orcas sink sailboat in latest ramming ‘game’ in Portugal
Five people were rescued after a pod of critically endangered Iberian orcas rammed into a sailboat several times, causing it to sink off Portugal’s Costa do Caparica, near the nation’s capital, Lisbon, on Sept. 13. None of the people on board suffered any injuries, according to the Portuguese maritime authority. The boat, owned by yacht […]
São Tomé and Príncipe commits to creating a marine protected area network
- São Tomé and Príncipe will establish eight marine protected areas (MPAs) covering 93 square kilometers (36 square miles) of coastal habitats in the Gulf of Guinea.
- The island nation aims to protect its marine environment while improving the lives of fishing communities, who rely heavily on fish for protein.
- Current challenges include the decline of pelagic fish stocks and loss of biodiversity due to indiscriminate fishing practices and climate change.
- The law designating the MPAs is expected to be enacted in September.

Pet sharks have become cool, but is owning them ethical?
- Owning a shark and keeping it in a home aquarium has become cool — and it’s no longer just the province of tech bros and celebrities.
- But experts note that most home aquariums are inadequate and can lead to stunted growth, deformities and early death.
- Yet sharks are often easy to buy, with some selling for as little as $90 online; zebra sharks (Stegostoma tigrinum), which are endangered, go for around $6,000.

Oysters could help fight climate change, study finds
New research from China suggests that oysters can be good at removing carbon dioxide from oceans, making the bivalves both an important food source and a potential tool in the fight against climate change and ocean acidification. Scientists have long debated whether oysters are a net source or sink of carbon dioxide (CO2) in the […]
Brazil weighs new measures to manage shark trade, fishing
- The Brazilian government is reviewing its legal framework for the trade in sharks, including fin exports and management of the fishery for blue sharks (Prionace glauca), the only species allowed to be caught in the country.
- At a Sept. 3 meeting, the National Environmental Council (CONAMA), a government advisory body, recommended the government ban shark fin exports and restrict the use of shark-fishing gear known as wire leaders.
- At the same meeting, the Ministry of Environment announced the suspension of an ordinance regulating blue shark fishing, including quotas, due to “increased pressure” on endangered species and flaws in monitoring and enforcement.
- The moves follow a recent Mongabay investigation revealing that government agencies sought to procure thousands of tons of shark meat for meals at public institutions including schools, hospitals and prisons. The exposé was cited at the Sept. 3 CONAMA meeting as well as in a class-action civil suit filed by conservation NGO Sea Shepherd Brasil seeking to ban federal public institutions from issuing tenders for shark meat.

An indestructible invasive anemone threatens Chilean Patagonia’s seas
- Native to the northern hemisphere, plumose anemones have spread across Chilean Patagonia.
- Scientists estimate that it was likely introduced in the late 20th century via ship ballast water.
- The exotic species occupies the seabed and displaces native communities of shellfish, mollusks and corals.
- The anemone’s presence is associated with a decline in biodiversity, and artisanal fishers are concerned.

Researchers describe three new-to-science snailfish species off California coast
In 2019, researchers surveying the seafloor off the coast of California came upon three unusual species of small fishes with large heads: one with bumpy pink skin, and the other two both black in color. The team collected the fish using underwater research vehicles and later analyzed their DNA and bodies. Their analysis showed that […]
Post-Blob, California’s kelp crisis isn’t going away
- Kelp forests function as major habitat for marine biodiversity, but are in rapid decline worldwide, largely because of climate impacts on the oceans.
- A 2013 marine heat wave known as “the Blob,” combined with the mass die-off of sea stars, caused a 95% loss of Northern California’s kelp forests.
- The loss of sea stars allowed the purple urchins that they thrive on to spread rapidly, converting lush kelp forests into “urchin barrens” in parts of California. There’s been very little recovery since.
- Restoration of kelp forests is extremely difficult and requires far more resources than are currently being committed.

Scientists reconfirm rare shark sightings after 50 years in PNG
In 1973, researchers scientifically described a species of shark based on a single specimen: a pregnant female caught a few years earlier by a fisherman near the mouth of the Gogol River in Astrolabe Bay, Papua New Guinea. They named this new-to-science species the sailback houndshark (Gogolia filewoodi). And then, for the next half-century, they […]
‘It doesn’t make sense’: Marine biologist on Kenya’s proposed nuclear power plant
- Kenya is considering building a nuclear power plant in Uyombo, a coastal town in Kilifi county. It would be near Mida Creek mangroves, Arabuko Sokoke Forest Reserve and Watamu National Marine Park and Reserve, all recognized for their high biodiversity, including endemic species and coral reefs.
- The plant’s cooling system could raise water temperatures in the area. This could harm marine life, potentially causing further coral bleaching and disrupting plankton and other critical species, which would, in the long run, affect the entire food chain.
- Residents and environmentalists, including marine biologist Peter Musila, have criticized the project and the government for poor communication, lack of public consultation and insufficient information on nuclear waste management.
- Musila argues Kenya does not need nuclear energy given the country’s renewable energy potential, and such a project raises concerns about potential accidents and long-term impacts on ecosystems and local livelihoods.

Sharks risk losing their bite as oceans turn acidic: Study
Sharks continually shed and regrow teeth throughout their lives, replacing worn or lost teeth with new ones. That makes them particularly good at catching prey. However, these top marine predators could lose their literal edge as ocean acidification damages their teeth and makes it harder to keep and replace them, a new study says. “Shark […]
Mongabay shark meat exposé sparks call for hearing and industry debate
- A Brazilian lawmaker said he would call for a parliamentary hearing after Mongabay’s shark meat investigation.
- Experts reacted to the investigation, saying the uncovered public tenders show greater extinction risk for sharks and urging stronger global protection.
- Industry groups called Mongabay’s investigation “alarmist,” defending shark meat’s safety and sustainability, despite warnings from scientists.

Why the BBNJ treaty on marine biodiversity matters more in the Mediterranean (commentary)
- The Mediterranean Sea covers less than 1% of the world’s ocean surface, yet hosts more than 18% of its known marine species, while being beset by unresolved maritime boundaries plus growing pressure from climate change, overfishing and pollution.
- That’s why this marine ecology hotspot needs the new U.N. treaty on oceanic biodiversity (BBNJ), as it offers a unique chance for Mediterranean countries to cooperate on common ground: despite claims that it lies outside of the scope of the agreement, there are legal grounds to claim the contrary.
- “Vast areas of the Mediterranean remain undelimited and unclaimed, existing in a legal gray zone. Under international law, these areas are considered de facto beyond national jurisdiction and therefore within the geographical scope of the BBNJ Agreement,” the authors of a new op-ed argue. “By mobilizing diplomatic, legal and financial resources through its institutions and member states, the EU can help catalyze broader regional ratification and implementation.”
- This post is a commentary. The views expressed are those of the authors, not necessarily of Mongabay.

Ghana passes landmark legislation to protect artisanal fisheries
- Ghana has passed a new fisheries act which aims at strengthening the artisanal fishery sector, restoring fish stocks and tackling problems with illegal, unregulated and unreported fishing.
- A major change is the expansion of the country’s inshore exclusion zone, which will double in size, expanding from 6 to 12 nautical miles (11 to 22 kilometers) from shore.
- The law has been welcomed by artisanal fishers who have been struggling with declining pelagic fish stocks due to destructive fishing practices within the IEZ.

Indonesia’s Bajau fishers lament nickel mining’s marine pollution
For many members of the nomadic Bajau sea tribe on Indonesia’s Kabaena Island, growing up meant swimming and fishing in clear waters, just outside their homes built on stilts. However, in 2010, the water turned red, which the villagers blame on runoff from nearby nickel mining, Mongabay’s Hans Nicholas Jong reported in July. “Now, I […]
Brazil cities vow to stop buying threatened shark meat after Mongabay probe
Several government agencies in southern Brazil have said they will stop ordering angelshark meat for public meal programs, in response to a Mongabay investigation that highlighted the widespread consumption of the threatened species. Shark meat is often served in public schools, hospitals and other institutions due to its low cost and lack of bones. The […]
Brazil cities order endangered angelshark meat despite fishing ban
Government agencies in Brazil’s Rio Grande do Sul state launched public procurements for more than 200 metric tons of meat from endangered angelshark species between 2015 and 2025, a Mongabay investigation has revealed. The meat is served in public institutions, including schools. Fishing for angelsharks is prohibited in Brazil, but its trade is legal if […]
Argentina’s elephant seals face 100-year recovery after avian flu devastation: Study
- At the end of 2023, an outbreak of avian flu devastated a colony of southern elephant seals in Argentina’s Valdés Peninsula.
- It may take a century for the population to return to the 18,000 breeding females it had in 2022, according to projections from a new study.
- Researchers estimate that 17,500 pups and an undetermined number of breeding adults died as a result of the outbreak, which also killed seabirds in the area.
- The previously healthy population is now vulnerable and faces an uncertain future.

Community efforts yield new marine protected area in the Philippines
The Philippines has officially designated a new marine protected area after an 18-year campaign by local communities, fisher associations, civil society organizations and government agencies, the Wildlife Conservation Society announced Aug. 13. The newly created Bitaug Marine Protected Area (MPA), which covers nearly 150 hectares (about 370 acres), is the largest MPA in Siquijor province […]
Belize project seeks out heat-resilient corals to protect its reefs
- An initiative called the Super Reefs program is setting out to identify the corals in Belize’s waters that have the highest chance of surviving warming waters amid climate change.
- Researchers with the program have discovered that corals that grow in the hottest areas are naturally more heat-resistant.
- Massive starlet coral (Siderastrea siderea) tends to be tolerant of warm water, whereas symmetrical brain coral (Pseudodiploria strigosa) is more sensitive.
- The team plans to use its findings, which are to be published by 2026, to inform the Belize government which coral communities in the country are best suited for protection and restoration.

Whale shark hotspot discovered along the Great Barrier Reef
- Whale sharks (Rhincodon typus) are the largest fish in the world and are endangered but are hard to study because they’re largely solitary creatures that roam great distances.
- There are only about 30 sites worldwide where they’re known to aggregate — and scientists have finally identified one of them along the Great Barrier Reef, a new study reveals.
- It’s the first known aggregation found in eastern Australia and in the entire southwest Pacific Ocean.
- The finding is significant for whale shark research and conservation efforts, experts said.
