The viperfish ( Chauliodus sloani) dangles a luminescent lure in front of its mouth and then snaps up any creature that dares to investigate. Other creatures use bioluminescence to detect or lure prey.

A male sea-firefly ( Vargula hilgendorfii) will squirt out a bright dot of light, zip upward, and then squirt another and another, essentially drawing an arrow that points out his whereabouts. Underwater, bioluminescence finds all manner of purpose. You’re odd man out if you don’t bioluminesce.” Two thousand years ago, the Roman scholar Pliny the Elder noted that if he rubbed the slime of Pulmo marinus, a jellyfish from the Bay of Naples, on his walking stick, it “will light the way like a torch.” Raskoff estimates that 90 percent of all the animals in the deep sea are in fact bioluminescent. In the deep sea, however, bioluminescence is found in virtually every type of animal: squids, octopuses, fishes, shrimps, single-celled organisms, and jellies of all kinds. It is most commonly seen among certain insect species like fireflies and glowworms (a form of insect larvae) some mushrooms and fungi also glow in the dark. Some acquire it through their diet others produce their own.īioluminescence is relatively rare on land. To glow on a regular basis, an organism must continually bring fresh luciferin into its system. When an ion such as calcium is present, an ensuing reaction emits light. Sometimes luciferin and luciferase are bound together with oxygen into a single molecule, or photoprotein. An enzyme called luciferase facilitates the reaction. This releases energy, and light is emitted. The glow occurs when a substance called luciferin reacts with oxygen. “The first time you see one of these animals just glow, it’s pretty amazing.”īioluminescence is light produced by a chemical process within a living organism. “It’s such a bizarre and exciting phenomenon to see,” agrees Steven Haddock of the Monterey Bay Aquarium Research Institute. “And that’s the natural light of the deep sea: bioluminescence.” “There’s a whole netherworld of the deep sea that we don’t see when we have our lights on,” says Kevin Raskoff, a scientist at California State University, Monterey Bay. Aequorea jellies glow with a bioluminescent protein used in the biotechnology industry.
