Near the intense volcanic CO 2 vents bubbling from the cracks in the seafloor, the water is so acidic that it dissolves coral skeletons. Read more about how reef scientist Laetitia Plaisance uses...
Local crafters who contributed to the Smithsonian Community Reef proved that there is no limit to the colorful reef forms that can be created using hyperbolic crochet techniques. Their wildly...
This close-up photograph of gold coral ( Gerardia sp. ) was taken at the Cross Seamount in the Pacific Ocean at a depth of 400 m (1,312 ft). Gold corals at this location can have lifespans of 2,000...
What happens to deep-sea coral samples after they are collected? In this image gallery, see some of the ways ocean scientists sort, measure, photograph, and study them. Learn more in the multimedia...
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...
An orange brisingid starfish sits on a large reef of Lophelia pertusa, cold-water corals in the Gulf of Mexico, at 450 m depth as a school of fish swims above. They have many arms—up to 20!—covered...

This specimen of the deep-sea coral Desmophyllum dianthus shows the visible bands that help marine scientists learn how ocean conditions changed over time. By looking at the thickness of each band,...
A coral ( Montastraea faveolata ) has just spawned. Each of the hundreds of polyps living in the colony releases a small pink bundle of sperm and eggs. Read more about coral spawing and watch a...
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,...
