Living deep-sea coral garden found off Benin, challenging decades-old reef death assumptions

Scientists using side-scan sonar and deep-sea cameras off Benin, West Africa, detected a living mesophotic coral garden about 54 meters deep, overturning decades of belief that this reef system was dead; the site hosts six octocorals, two black corals, and at least eight reef fish species with no observed bleaching, marking the first confirmed mesophotic reef on the Gulf of Guinea shelf. Researchers plan to collect samples to assess health and resilience amid climate-driven warming.

Rolling-meadow giant: citizen scientists uncover one of the reef's largest coral colonies

Citizen scientists identify a Pavona clavus coral off Cairns spanning about 111 meters and covering roughly 3,973 square meters, potentially making it one of the reef’s largest colonies. Genetic testing is needed to confirm if it is a single organism or multiple close colonies, with size mapped via photogrammetry and implications for reef resilience.

Citizen scientists uncover world’s largest coral colony off Australia

A mother-daughter team with Citizens of the Reef identified the world’s largest known coral colony on the Great Barrier Reef—a Pavona clavus spanning about 111 meters and covering roughly 3,973 square meters—verified by underwater measurements and a 3D model; the exact location isn’t released to protect the site, and the find underscores the value of citizen science in reef monitoring amid ongoing bleaching.

Cauliflower Coral Crown: A Mind-Bending Win for Close-Up Photographer of the Year

Australian photographer Ross Gudgeon won the grand prize at the Close-Up Photographer of the Year with an extreme close-up of a cauliflower-soft coral in Indonesia’s Lembeh Strait, captured using an underwater probe lens; the 7th edition drew over 12,000 entries from 63 countries across multiple macro and micro categories, highlighting tiny wonders from mayflies and stingless bees to moths and frogs in vivid, intimate detail.

34-Meter Sea Giant Predating Napoleon Discovered Alive

Scientists have discovered a massive 34-meter-wide coral colony off the Solomon Islands, believed to be the largest living organism on Earth, dating back to the time of Napoleon. This Pavona clavus coral, over 300 years old, showcases remarkable resilience amidst environmental changes, offering hope for coral conservation amid climate change challenges. The discovery, made during a National Geographic expedition, highlights the unexplored wonders of the ocean and has spurred local conservation efforts to protect the area.

Unusual Bacteria Found in Deep-Sea Coral

Scientists have discovered two new species of bacteria, Oceanoplasma callogorgiae and Thalassoplasma callogorgiae, in deep-sea coral in the Gulf of Mexico. These mollicutes have extremely small genomes, with only 359 and 385 protein-encoding genes, compared to the average bacterium's 3,000. They survive symbiotically in the coral's mesoglea, obtaining energy from an amino acid rather than carbohydrates. The discovery highlights the minimal genetic requirements for cellular life and introduces a new bacterial family, Oceanoplasmataceae.

World's Largest Coral Discovered, Visible from Space

Scientists have discovered the world's largest coral in the southwest Pacific Ocean, visible from space and estimated to be over 300 years old. This massive coral, found during a National Geographic Pristine Seas expedition, is three times larger than the previous record-holder and provides a habitat for diverse marine life. While the discovery offers hope for coral resilience, it also highlights the threats posed by climate change and human activities. The finding coincides with global climate discussions at COP29, emphasizing the need for increased efforts to combat carbon emissions.

Massive 300-Year-Old Coral Discovered in Pacific, Visible from Space

Scientists have discovered the world's largest coral in the Pacific Ocean near the Solomon Islands, measuring 34 meters wide and potentially over 300 years old. Found by a National Geographic team, this coral is in good health despite global warming threats, likely due to its deeper location. The discovery highlights the importance of protecting marine ecosystems, especially for small island nations like the Solomon Islands, which rely heavily on marine resources. The find coincides with COP29 climate talks, emphasizing the need for increased financial support to combat climate change impacts.
