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...
Stare at a tide pool and you will often see a crust of pink coating the bottom. No, this is not bubblegum from some careless teenager’s shoe: it’s a stony kind of seaweed that, like other seaweeds,...
Peter Auster and colleagues direct a Remotely Operated Vehicle (ROV) dive on the New England Seamounts. Three teams composed of three scientists and four ROV engineers take two 4-hour watches every...
This 200-year-old bamboo coral colony is growing on the Davidson Seamount off the coast of California. The skeleton of this deep-sea coral has bamboo-like segments. See more pictures of coral in our...
The pink strands of this single deep-sea coral harbor a variety of marine life. Sea whips are gorgonian corals and have flexible skeletons. See more pictures of coral in our Deep-sea Corals article.
Close to the volcanic CO 2 seeps, the vast diversity of corals that exists in less-acidic waters is replaced by a "monoculture" of boulder corals. These are less fragile and better suited to life in...
A piece of the Institute For Figuring’s Hyperbolic Crochet Coral Reef known as the Ladies Silurian Atoll. The HCCR exhibit was on display in the Sant Ocean Hall at the Smithsonian's National Museum...
Compare the healthy coral on the left with the bleached coral on the right. Increased water temperatures caused the bleached coral to lose the microscopic algae that give the coral color and provide...
A large white coral (Corallium sp.) grows on the Balanus Seamount, part of the New England Seamount chain. Hanging on to the coral are stalkless crinoids and orange brittlestars (Opiacantha sp.) To...
You may not think of the ocean as a pharmacy but scientists are developing exciting new medicines from the sponges, corals, and other marine organisms found in the sea. Explore other videos that...
The Autonomous Underwater Vehicle (AUV) SeaBed, shown here as it is about to be deployed, has been used to survey deep-sea fishes and coral habitats. Learn more about how underwater vehicles study...
What is coral bleaching? These white corals in the Gulf of Mexico’s Flower Garden Bank National Marine Sanctuary are bleached due to an increase in water temperatures, which causes corals to lose the...
GEOMAR scientist Armin Form works at his lab during a long-term experiment on the effects of lower pH, higher temperatures and "food stress" on the cold-water coral Lophelia pertusa . In a previous...
Smithsonian zoologist Dr. Steve Cairns named and described this deep-sea coral species, Stephanocyathus paliferus, which is now preserved in the collections of the National Museum of Natural History...
Inside the control van for the remotely operated vehicle (ROV) Jason , Dr. Brendan Roark and colleagues watch the ROV collecting deep-sea coral specimens. No scientists dive down with their ROV, so...
Imagine you’re an alien seeing Planet Earth for the first time. What do you see from your spacecraft? A blue planet with over 70% of its surface covered by ocean. From space it’s obvious how...
When he was 10 years old, Stephen Cairns lived in Cuba where he kept a collection of butterflies and sea shells. When his family moved to Louisiana, he could bring only one of the collections with...
