The Vashishti River, originating in the biodiversity-rich Western Ghats and flowing into the Arabian Sea along India’s western coast, has long supported traditional fishing communities. But in 2023, local fishers encountered something entirely unexpected. As they hauled a gill net into a boat, a gray body, still making faint movements, emerged tangled in the mesh, and then another surfaced beside it. By the time the net was lifted aboard, three bull sharks (Carcharhinus leucas) were tangled inside. The video of the incident quickly spread across social media, drawing renewed scientific attention to the presence of sharks in inland and estuarine waters. “This is the first documented report of sharks from the Vashishti River, although historically sharks and rays have been recorded from several major Indian river systems,” Priyankar Chakraborty, an independent marine and wildlife researcher in India, told Mongabay. Across India, dozens of species of sharks and rays (collectively known as elasmobranchs) have been reported as inhabiting estuaries and rivers, but while species such as the bull shark are relatively well documented, many others are known from only a handful of records, leaving major gaps in understanding, Chakraborty said. Globally, around 60 species of sharks and rays spend at least part of their lives in inland waters. Yet compared with their marine counterparts, these species have received remarkably little scientific attention, even though many are among the most threatened vertebrates on Earth, Michael Grant, a marine biologist at James Cook University in Australia and member of the IUCN Species Survival…This article was originally published on Mongabay
During a recent monthlong expedition, a team of scientists conducted one of the most comprehensive surveys ever undertaken in the deep waters of Trinidad and Tobago, a dual-island nation located in the southern Caribbean Sea. Nearly 93% of the country’s waters are deeper than can be reached by recreational scuba diving, making it impossible to map them without specialized equipment. This expedition, which took place between June 29 and July 28 onboard the California-based Schmidt Ocean Institute’s research vessel R/V Falkor (too), helped fill major gaps about Trinidad and Tobago’s deep-sea environment by deploying remotely operated vehicles and other technology in the nation’s deep waters. The scientific team documented dozens of active cold seeps and species believed to be new to science, and mapped about 13% of the country’s marine territory, according to a press release. The expedition also marked a milestone for Caribbean science. It was led by deep-sea ecologist Diva Amon, a Trinidad and Tobago native and co-founder of SpeSeas, an organization that works to advance marine science, education and conservation across the country and the wider Caribbean. Amon, who is also a scientific advisor at the Benioff Ocean Science Laboratory at the University of California, Santa Barbara, was joined by fellow scientists from across the Caribbean as well as from the U.S., Canada and Spain.

The scars of bottom trawling are still visible on seamounts in Chile’s Juan Fernández Archipelago, even 25 years after the fishing practice took place in the area, according to a new study. In 2024, scientists from Chile and the U.S. used remotely operated vehicles aboard the Schmidt Ocean Institute’s research vessel R/V Falkor to survey four seamounts, underwater mountains that rise up from the seafloor, off Chile’s coast. Three of the seamounts are located in the Juan Fernández Archipelago, a cluster of volcanic islands that has one of the highest known rates of marine endemism on the planet. An estimated 62% of the reef fish species of Juan Fernández and the neighboring Desventuradas Islands are found nowhere else in the world. Other unique endemic species include the Juan Fernández fur seal (Arctocephalus philippii) and the Juan Fernández rock lobster (Jasus frontalis). The fourth study site was the Solito Seamount, located north of the Juan Fernández Archipelago and known to harbor similar marine communities. In the late 1990s and early 2000s, fishers conducted bottom trawling on the Juan Fernández seamounts, dragging weighted nets across the seafloor to catch orange roughy (Hoplostethus atlanticus) and alfonsino (Beryx decadactylus), long-living, deep-sea fish. After catches dwindled, these fisheries collapsed and the trawling stopped. Later, in 2015, Chile permanently banned bottom trawling on all of its seamounts. At Solito, by contrast, the study, published in July in Deep Sea Research, found no evidence that bottom trawling had ever occurred. Twenty-five years after bottom trawling had taken…This article was originally published on Mongabay
Thirteen beluga whales, part of a pod of about 30 that were left languishing in a shuttered Canadian theme park, arrived in the U.S. The first transfer of six whales happened on July 21, and another seven were shipped out on August 3. These whales are part of the emergency transfers from Canada’s Marineland to their new homes in the U.S., marking the beginning of the end to a year-long saga of uncertainty. Shipped in specialized, cold-water containers, the belugas (Delphinapterus leucas) traveled for hours, on trucks and a plane, to two U.S. facilities: nine individuals went to SeaWorld in San Antonio, Texas, and four females to Shedd Aquarium in Chicago, Illinois, in two batches. Marine mammal veterinarians accompanied the cetaceans throughout their journeys, according to a press release from Georgia Aquarium. A spokesperson from the Atlanta-based aquarium said in an email it hopes to receive two beluga whales from Marineland in subsequent transfers. The international transfer came to fruition after several aquariums, all accredited with the U.S.-based Association of Zoos and Aquariums (AZA), drew up an emergency rescue plan earlier this year to transfer the belugas out of Marineland. These cetaceans had spent years at the theme park in Niagara Falls, Ontario. In 2019, Canada passed the landmark Ending the Captivity of Whales and Dolphins Act, which banned the keeping, breeding and trading of cetaceans — whales, dolphins and porpoises — for entertainment, affecting Marineland’s business model. By 2021, Marineland was Canada’s only entertainment park with cetaceans and was…This article was originally published on Mongabay
On Sunday, April 26, Argentine officials stopped an unusual shipment arriving at an airport near Buenos Aires. Inside, they found so many dead and dying fish, octopuses and crabs that a national rescue center had to install 10 new emergency tanks to support the survivors. It was the third time in a year authorities had seized an illegal shipment of sea life at the same airport, the Associated Press reported. Marine wildlife trafficking is a growing global business, driven by demand for ornamental fish, luxury foods and traditional medicines. Much of that trade is routed through airplane luggage or airmail, where the vast majority of animals, dead or alive, go undetected. The combined use of artificial intelligence (AI) and 3D X-ray machines could change that, according to an international team of researchers. Training an algorithm on samples of seahorses, shark fins and sea cucumbers, the scientists achieved successful detection rates between 86% and 96%, according to a research paper published last week. “As it stands, our methods of detecting something that shouldn’t be in our bags on the front line is reliant on human inspection and biosecurity dogs,” Vanessa Pirotta, a marine biologist at Macquarie University in Australia and the paper’s lead author, told Mongabay. “AI could be used to complement that. It’s not a silver bullet, but an assistant and a tool.” Image from the study showing (from top to bottom) shark fin, seahorse and sea cucumber samples next to a security X-ray of each item.

In 2018, night patrol teams on Boa Vista, the third-largest island in the Cabo Verde archipelago, started noticing a change along the beaches: The loggerhead turtles were arriving in significantly larger numbers than usual. In previous years, each team, comprised of staff and volunteers from local conservation NGO Cabo Verde Natura 2000 (CVN2), encountered between five and 10 female turtles (Caretta caretta) a night. But now, the teams were each recording between 20 and 30 females a night. By 2021, that number had grown to between 30 and 40. A recent study published in Biological Conservation confirms the upward trend: An 80-fold increase in the population of loggerheads nesting at three of Boa Vista’s beaches over 27 years, from 1998 to 2024. The authors of this first long-term study of Cabo Verde’s nesting loggerheads ascribe the remarkable trend to decades-long conservation efforts at the local and national level. Loggerheads, which primarily inhabit temperate and subtropical regions of the Pacific, Atlantic and Indian oceans and the Mediterranean Sea, are long-lived, slow-maturing migratory animals. With a lifespan of 80 years or more, female loggerheads take decades to reach sexual maturity. The global loggerhead population has declined by 47% over the past three generations, according to the last IUCN Red List assessment, where it remains listed as a globally ‘vulnerable’ species. The IUCN, the global wildlife conservation authority, largely attributes this decline to anthropogenic pressures such as habitat loss, marine pollution, bycatch, poaching and multiple climate change-driven impacts.

Food packaging ranks among the top plastic pollutants littering the world’s coastlines, a new study confirms. The study, published May 20 in the journal One Earth, analyzed data from 112 nations, including 5,300 shoreline litter surveys, to produce the first global index of macroplastic pollution by usage type. Based on 355 peer-reviewed studies, it found that food and beverage plastics were the most common litter type for 93% of the countries surveyed. Within that category, food packaging, caps and lids, and plastic bottles were the most consistently found items, appearing as the top three across more than half of surveyed countries. This included the world’s five most populous countries: China, India, the United States, Indonesia and Pakistan. Plastic bags and cigarettes followed as the next most prevalent categories. The study’s lead author, Max Richard Kelly of the University of Plymouth in the U.K, said he was not surprised by the volume of food and beverage plastics on beaches but was struck by similarities in the surveyed countries. “Seeing the exact pattern replicated across the vast majority of nations was a stark reminder of the true scale of crisis we are facing,” he told Mongabay in an email.

VJOSA-NARTA, Albania — In late April, heavy machinery began moving into the Pishë Poro-Narta protected landscape on Albania’s Adriatic coast without permits or public notice. Bulldozers and excavators felled coastal pine trees, flattened sand dunes, and cut new roads through previously untouched habitat. Then, barbed wire fences went up along the shoreline. The incursion was the realization of a luxury resort development backed by Jared Kushner, U.S. President Donald Trump’s son-in-law. The development plans of Kushner’s Affinity Partners, a private equity fund, stretch from the uninhabited Sazan Island into the Vjosa-Narta Protected Landscape, the delta region of Albania’s Vjosa River that includes Pishë Poro-Narta. Roughly twice the size of Paris, the Vjosa-Narta area shelters flamingos, Dalmatian pelicans (Pelecanus crispus), loggerhead sea turtles (Caretta caretta) and more than 70 endangered species, among them the Mediterranean monk seal (Monachus monachus). Neither Affinity Partners nor the office of the prime minister of Albania responded to Mongabay’s requests for comment.

When protesters arrived at the site, security guards confronted them. Video of a demonstrator being dragged across the dunes on May 30 near the village of Zvërnec went viral. Soon demonstrations erupted in Tirana, the Albanian capital, in what has since been dubbed the Flamingo Revolution. The protests have grown larger every day, with tens of thousands demanding accountability for corruption, an end to…This article was originally published on Mongabay
PORT HUGHES, Australia — Situated midway along the Great Southern Reef that spans Australia’s southern coastline, the waters off Port Hughes typically teem with life. The coastal hamlet northwest of Adelaide plays host to a multitude of coral, bivalve and fish species. But in late March, the largest and longest harmful algal bloom (HAB) in Australian history arrived to Port Hughes, depleting its waters’ rich biodiversity. The bloom had first appeared elsewhere off the state of South Australia’s coast a year earlier, causing eye and skin irritation and respiratory symptoms among beachgoers. Then, along with waves of acrid-smelling sea foam, scores of dead marine animals began washing ashore. In Port Hughes, the HAB’s impacts were most visible below the surface. The town’s wooden jetty had previously been one of the most consistent locations in South Australia to observe temperate species, said Stefan Andrews, co-founder of the Great Southern Reef Foundation, a conservation advocacy group. But by mid-April, when Mongabay joined Andrews on a dive, the site was drab compared with vibrant photographs taken in February and March. Under the jetty, sponges and corals that had previously adorned its pylons in a brilliantly hued mosaic appeared colorless. Apart from a short-headed seahorse (Hippocampus breviceps) — a “sign of hope,” Andrews called it — little life was visible in the murky waters. The reef, he said, had become quieter, lacking the sounds of snapping shrimp and other creatures that once played in the underwater soundtrack. “There’s a sense of loss when you…This article was originally published on Mongabay
JEJU ISLAND, South Korea — In April 2025, I zipped myself up into a thick wetsuit and inched down a steep, rocky ledge toward the gray-blue water encircling Beomseom, a small island off the southern coast of Jeju Island in South Korea. Then I leapt into the chilly sea and wriggled into my scuba gear while floating on the surface. In the water with me was Sanghoon Yoon, an adviser for Paran Ocean Citizen Science Center, a South Korean civil society group that advocates for the protection of the ocean. That day, Yoon was my scuba dive buddy. Yoon and I sank beneath the dangling legs of snorkelers into a watery realm of rocks and kelp. Once in deeper water, I encountered gelatinous stalks of soft coral. The polyps appeared purple, pink, red, and even orange, depending on the light.

Sanghoon Hoon, an adviser to the Paran Ocean Citizen Science Center, dives among corals in the waters off Jeju, South Korea. Image courtesy of Paran. The soft corals I saw that day were healthy. But in 2024, soft corals around Beomseom Island and other parts of Jeju experienced what scientists are calling a “slumping” event — and what Yoon describes as “melting” — which saw soft corals losing their shape, drooping, and even dying. The event was widely reported in local media and attributed to marine heat as Jeju waters hovered…This article was originally published on Mongabay
As offshore wind farms expand rapidly in the global renewable energy transition, scientists are studying how these large marine infrastructure projects affect ecosystems beneath the waves. Research from Wageningen University & Research in the Netherlands suggests that offshore wind may bring both risks and benefits for sharks and rays, known collectively as Elasmobranchii, which are highly sensitive to electromagnetic fields (EMFs). A six-year project called “Elasmopower” examined how EMFs from subsea power cables in offshore wind farms affect bottom-dwelling sharks and rays. These species depend on natural electric and magnetic fields for key behaviors such as navigation, prey detection, habitat use and long-distance movement, particularly in low-visibility environments. The studies conducted as part of the Elasmopower project have been published in four papers, with three additional papers currently undergoing peer review. Sharks and rays have specialized electroreceptors called ampullae of Lorenzini. The jelly-filled sensory canals around the head and snout can detect even extremely weak EMFs from prey and predators, water movement, and the Earth’s geomagnetic field, Erwin Winter, a scientist at Wageningen, told Mongabay. This system is central to hunting and orientation, making Elasmobranchii especially relevant for studying EMF exposure from offshore energy infrastructure, Winter added. Erwin Winter, a researcher with the Elasmopower project, presented findings on offshore wind, electromagnetic fields and bottom-dwelling sharks and rays at the Sharks International 2026 conference in Colombo, Sri Lanka, in May.

The French government recently announced it has greenlit a plan to send its last captive cetaceans — two orcas and 12 dolphins — to zoos and entertainment parks in Spain. These cetaceans live in the Marineland Antibes park on the French Riviera, which closed in 2025. In 2021, France passed a law banning the breeding and keeping of cetaceans in captivity for entertainment shows, which will come into effect on Dec. 2, 2026. The orcas and dolphins at Marineland were the primary draw for visitors. The two orcas (Orcinus orca), Wikie, aged 25, and her son, Keijo, aged 12, were born at Marineland Antibes on the French Riviera and spent all their lives in concrete tanks and performing in display shows. They will now be moved to Loro Parque, a zoo and entertainment park in Tenerife on the Canary Islands. The dolphins will be split up between two parks in Valencia and Málaga on the Spanish mainland, with plans for some of them to return to France’s Beauval Zoo, when it’s ready to have them, according to reporting by Le Monde. A court-appointed expert team found in February 2026 that the concrete tanks in which the orcas lived at Marineland Antibes were in advanced structural decline, and if the mammals weren’t moved soon, they would have to be euthanized. “Faced with this emergency, we are acting to avert the worst,” Mathieu Lefèvre, France’s minister delegate for ecological transition, said in a statement, explaining the rationale for the decision. “Loro Parque…This article was originally published on Mongabay
