This aptly named fish ( Anoplogaster cornuta ) has long, menacing fangs, but the adult fish is small, reaching only about 6 inches (17 cm) in length. It's teeth are the largest in the ocean in...
Dive through the zones of the ocean to the deep ocean bottom, where many strange species live, and there are many yet to be discovered. Explore them in the Deep Ocean Exploration section.
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...
Deep-sea coral beds are true biodiversity hotspots. It’s urgent that we study these extreme environments because we know so little about them, because they are important communities for so many deep-...
In the icy waters of the Arctic , a deep-water larvacean (aka “sea tadpole” because it looks like a tadpole) drifts through the water in its 'house.' This house is made of protein and creates almost...
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...
In this episode of the Podcast of Life , host Ari Daniel Shapiro dives deep to discover a white worm as tall as your refrigerator that breathes through bright red feathery "lips." This isn’t a...
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...
Deep below the ocean’s surface is a mysterious world that takes up 95% of Earth’s living space. It could hide 20 Washington Monuments stacked on top of each other . But the deep sea remains largely...
Off the coast of North Carolina, Dr. Martha Nizinski and Johnson Sea Link pilot Phil Santos descend through the water column toward the target site. During this dive, Nizinski will observe and record...
Flower-like zoanthids, relatives of coral, carpet a hydrothermal vent. This species of zoanthid is the first ever discovered at a hydrothermal vent. See more pictures of incredible deep sea diversity...
Methane gas, trapped deep within the Earth's crust, can slowly leak from cracks in the seafloor known as methane seeps. While we would never consider methane as food, in the deep sea where there is...
Sample the surprising diversity of deep-sea corals. See some of the ways they differ in color, shape, and size. Explore more in the multimedia feature " Coral Gardens of the 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...
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...
Watch a Discovery video on Smithsonian squid expert Clyde Roper’s search for giant squid in Kaikoura Canyon off the coast of New Zealand. More about giant squid can be found in our Giant Squid...
This crab ( Neolithodes sp. ) was collected on a NOAA/MAR-ECO cruise to the Mid-Atlantic Ridge in the summer of 2009. Its red color provides camouflage and protection from predators. Red wavelengths...
I still haven’t gotten beyond the ‘gee whiz’ factor of studying communities of animals in deep-sea coral habitats. Climbing over undersea mountains and along the steep cliffs of submarine canyons...
