Deep below the ocean’s surface is a mysterious world that takes up 95% of Earth’s living space. It could hide 20 Washington...
After ocean scientists sort deep-sea corals according to their different types, they carefully measure and photograph the specimens. Find out how ocean scientists study deep-sea corals in our Deep-...
Like its terrestrial namesake, the Venus fly-trap anemone ( Actinoscyphia sp.) sits quietly and waits for food to drift into its outstretched tentacles, which are lined with stinging harpoons called...
A sea star , Hymenaster pellucidus , brought up from a benthic ROV dive. View the “Under Arctic Ice” photo essay to learn more.
Come along as scientist Dr. Brendan Roark narrates a submersible dive to collect and study deep-sea corals. Roark studies deep-sea corals to understand the history of the ocean and past ocean...
The goblin shark ( Mitsukurina owstoni ) is one of the creepier fish out there! It has a long, prominent snout covered with special sensing organs (ampullae of Lorenzini) that help it to sense...
On the deep seafloor of the Gulf of Mexico, ecosystems made up of fish, corals, sea stars, anemones and other invertebrates flourish. Since the sun’s rays don’t reach the deep sea, coral communities...
Travel to a world of perpetual night--the deep ocean hydrothermal vents near the Galapagos Rift where life thrives around superheated water spewing from deep inside the Earth. Discovered only in 1977...

You may have seen the sparkle of fireflies on a summer’s night. The fireflies produce light through a chemical reaction in their glowing abdomens, a process known as bioluminescence. But did you know...
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 icy cold and the light dim or absent. Yet believe it or not, lush coral...
Dr. Amy Baco-Taylor observed corals like these on her first submarine dive to a deep-sea coral bed off the coast of Hawaii. They include primnoids, zoanthids, and Gerardia . The high density and...
