What does a bioluminescent creature that lives more than 2 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...
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...
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...
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...
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...
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...
Under white light, this shortnose greeneye fish ( Chlorophthalmus agassizi ) looks unimpressive. But, in dim blue light—the type usually seen at depth—it shows its true fluorescent colors. NOAA...
This copepod ( Gaussia princeps ) was collected deeper than 1000 meters in the Sargasso Sea by Census of Marine Zooplankton (CMarZ) researchers in April 2006, as part of the 10-year Census of Marine...
The deep-sea dragonfish ( Stomiidae ), also called the barbeled dragonfish, uses it's fang-like teeth to grab prey in its deep-sea environment . Like other deep-sea organisms, dragonfish have...
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,...
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 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...
This lanternfish ( Diaphus sp .), found in the Red Sea, has light-producing photophores along its ventral surface (belly), and a nasal light organ that acts like a headlight. Hear scientists tell...

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 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...
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...
Tropical hatchetfish ( Argyropelecus lychnus ), like the one shown in this X-ray photograph, live in the dark depths of the ocean ; this specimen was collected at about 2,789 feet (850 meters) in the...
