It may be the last place you’d expect to find corals—up to 6,000 m (20,000 ft) below the ocean’s surface, where the water is...
The robotic arm of the Jason, a Remotely Operated Vehicle (ROV), collects several stalks of black coral from the seafloor. Read more about how underwater vehicles help ocean scientists study deep-sea...
Marine scientists photographed and measured this gorgonian coral (Chrysogorgia sp.) and deep-sea shrimp (Bathypalaemonella sp.) just as they were collected—together. Find out how ocean scientists...
The research submersible Alvin uses bright lights to illuminate the dark seafloor. Built in 1964, it has made more than 4,400 dives. It can carry two scientists and a pilot as deep as 4,500 meters (...
The robotic arm of a Pisces submersible collects a gold coral colony ( Gerardia sp.) during a research cruise in the Hawaiian Islands. Ocean scientists have radiocarbon-dated some Gerardia specimens...
Artist Shih Chieh Huang spent a good part of 2007 exploring specimens of deep-ocean animals found in the collections of the National Museum of Natural History . He was a Smithsonian Artist Research...
Riftia tubeworm ( Riftia pachyptila ) colonies grow where hot, mineral-laden water flows out of the seafloor in undersea hot springs—such as the Guymas Basin of the Gulf of California at 2,000 meters...
Giant squid have the largest eye in the animal kingdom. At up to 10 inches in diameter, people often describe it as the size of a dinner plate -- or, in other words, as big as a human head. Here,...
Sunset? Time to glow! A biological clock triggers bioluminescence in the dinoflagellate Pyrocystis fusiformis . At dusk, cells produce the chemicals responsible for its light. Hear from marine...
The yellow bioluminescent ring on this female octopus ( Bolitaena pygmaea ) may attract mates. Bioluminescence is an important adaptation that helps many deep sea animals survive in their dark world...
