This beautiful jewel squid ( Histioteuthis bonnellii ) can be found swimming above the Mid-Atlantic Ridge, at depths of 500-2,000 meters (1,640-6,562 feet). The “jewels” covering the body are...
The mauve stinger’s ( Pelagia noctiluca ) name in German means “night light,” referring to the jelly’s reddish coloring and its bioluminescence, the display of light by a living creature. Unlike a...
A fringe of short tentacles surrounds the flattened bell of this tiny, transparent jellyfish ( Halicreas minimum ), which can be found at depths up to 984 feet (300 meters). But it would be hard to...
Watch as barnacles feed on bioluminescent dinoflagellates. Barnacles are crustaceans (like crabs, shrimps and lobsters) that secrete their shells for protection while living attached to things like...
What does a bioluminescent creature that lives more than two miles below the surface of the ocean and a glow stick have in common? More than you think. In a unique spin on an art technique called "...
Dr. Edie Widder spoke at the National Museum of Natural History as a part of the Changing Tides Lecture Series and discussed her work on underwater light: light chemically produced by animals through...
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...
“It’s a little appreciated fact that most of the animals in our ocean make light,” says Edie Widder, biologist and deep sea explorer at ORCA. In this TED talk, she shows incredible film and photos...
The ROV Hyper Dolphin caught this deep-sea jelly (Atolla wyvillei) on film east of Izu-Oshina Island, Japan. When attacked, it uses bioluminescence to "scream" for help—an amazing light show known as...
Bioluminescence is one of the more captivating adaptations that have evolved in marine animals. It's the ability of organisms to create and emit light. Dive underwater and you may witness lightshows...

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...
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...
The Census of Marine Life - a ten-year effort by scientists from around the world to answer the age-old question, “What lives in the sea?” It was an international effort to asses the diversity,...
“Upon returning from the reef after a night dive, I swam toward a bright reflection and came eye-to-eye with this beautiful, curious squid," said Charles Viggers, a Nature's Best photographer. Squids...
The fish at left stands out against the lighter waters above. At right the same fish—now with bioluminescent structures on its underside lit—blends in. Many deep sea creatures have evolved this...
