A large shark named Bukangi has been trapped in a canal in South Korea’s port city of Busan for nearly two weeks, drawing hundreds of thousands of visitors. Despite failed attempts by authorities to guide the animal back to the open sea, the shark has become a local mascot and social media sensation, prompting officials to plan a new release effort using a large net.
Scientists have discovered living glass sponge reefs off the coast of British Columbia, Canada, overturning the belief that these silica-based ecosystems vanished 40 million years ago. These deep-sea structures, some reaching 80 feet in height, are now protected but face threats from fishing and climate change.
Two studies tested attaching glass or plastic bottles to gillnets to boost dolphins’ ability to detect nets via echolocation. Results varied by region: in Peru and Zanzibar the bottles had mixed or limited effects (Peru saw more fish but no clear dolphin reduction; Zanzibar saw more tuna with no dolphin data to conclude), while in Brazil, bottom-set nets with bottle reflectors reduced dolphin bycatch by about 88% without harming target fish. The authors suggest the approach is low-cost and scalable, warranting further trials elsewhere to confirm effectiveness.
Scientists rediscovered a healthy mesophotic reef off Benin, West Africa, more than 60 years after it was first hinted at, hosting at least eight coral types and eight fish species (including soft corals and black corals). The reef lies about 175 feet below the surface and bridges shallow and deep habitats, offering opportunities for paleoclimatic study and carbon dating, with plans to seek protection and hopes that the Gulf of Guinea becomes a regional hub for marine science.
A new study maps coral reefs and identifies about 64,000 square miles that appear capable of withstanding warming oceans, highlighting priority areas for targeted conservation and restoration to protect biodiversity and livelihoods as climate change progresses.
As the ocean warms, mesothermic predators like great white sharks and certain tuna must burn more energy to stay warm, forcing them to relocate to cooler waters and cope with dwindling prey; sensor data show that a one-ton warm-bodied shark may struggle to stay in water above about 62.6°F (17°C), highlighting overheating risk alongside ongoing threats from overfishing and bycatch.
Coral reefs, vital to marine biodiversity, are nearing a potential catastrophic collapse due to increasing ocean heatwaves, especially around 2026, driven by climate change and El Niño cycles. While some reefs show resilience, many are at risk of irreversible damage, emphasizing the need for urgent global action to reduce emissions and local stressors to preserve these ecosystems.
Scientists exploring the deep-sea ridge near Hawaii discovered a mysterious 'yellow brick road' formed by fractured volcanic rock, highlighting the vast unexplored areas of Earth's seafloor and offering new insights into underwater geology and ecosystems.
Scientists exploring the deep-sea ridge near Hawaii discovered a mysterious 'yellow brick road' made of fractured volcanic rock, highlighting the vast unexplored areas of Earth's ocean floor, with only about 0.001% of it visually documented so far.
NASA's Aqua satellite has successfully detected dense patches of the tiny red plankton Calanus finmarchicus off the New England coast, a crucial food source for the endangered North Atlantic right whale, using innovative remote sensing techniques. This breakthrough allows for better monitoring of marine ecosystems and could help protect whales by predicting their movements and reducing human-related threats.

The Sargasso Sea, unique for having no land boundaries and characterized by floating Sargassum seaweed mats, plays a crucial role in marine ecosystems and Earth's climate regulation, but faces threats from pollution and climate change that require international conservation efforts.
Deep technical divers in Indonesia captured the first-ever live footage of a Sulawesi coelacanth in its natural habitat, confirming its survival and extending its known range, highlighting the species' rarity and the need for conservation efforts.
Sightings of giant jellyfish, particularly the barrel jellyfish, have surged around the UK coast this year, likely due to rising sea temperatures and changing currents, with ecological shifts also affecting other marine species; meanwhile, sightings of the Portuguese man o’ war have decreased significantly.
Researchers exploring Antarctica's Weddell Sea during the search for Shackleton's ship discovered over 1,000 organized fish nests of yellowfin notie, revealing a unique and vulnerable ecosystem that highlights the importance of marine conservation and the resilience of life in extreme environments.
