More Bioluminescence

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...
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...
This transparent cockatoo squid ( Leachia sp.), also known as a glass squid, lives in the depths of the ocean and has many adaptations to help it survive there. It retains ammonia solutions inside...
Scientists describe the amazing bioluminescent creatures they encounter as they descend into the deep--siphonophores, ctenophores, and viperfish--in this Smithsonian/History Channel "Deep Ocean...
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. Bioluminescence is the process by which living...
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...
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,...
Glowing photophores are visible on this midwater squid ( Abralia veranyi ) viewed from below at low light levels. We think of light as a way to see in the dark. But many species use it to help them...
Jellyfish and comb jellies are gelatinous animals that drift through the ocean's water column around the world. They are both beautiful—the jellyfish with their pulsating bells and long, trailing...
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...
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...
Artist Shih Chieh Huang assembling one of his installations. Huang was a Smithsonian Artist Research Fellow in 2007 and spent his time studying bioluminescent marine animals . That research has...
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...
“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...
These southern elephant seals ( Mirounga leonina ) may look like beach bums, but when they are in the water hunting, they are anything but. Satellite tracking by tagging the animals has found that,...
“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 long barbel on the chin of this dragonfish ( Stomias boa ) has a glowing tip that may attract prey. With its large mouth and sharp, curved teeth, the fish makes quick work of any prey that...
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...
