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...
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...

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...
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...
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...
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...
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...
Artist Shih Chieh Huang spent a good part of 2007 exploring specimens of deep-ocean animals found in the collections of the National Museum of Natural History . He was a Smithsonian Artist Research...
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...
Artist Shih Chieh Huang creates work using plastic bags, household objects, computer cooling fans, LED lights, and other assorted materials. His 2011 solo exhibition, " The Bright Beneath: The...
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 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...
