	Anemaw [Animal Electromagnetism and Waves] : Bioluminescence . © Elizabeth Gerrow 2002 .
		Organisms possessing bioluminescence include, but may not be limited to, varying species of more than forty orders or groups of bacteria, fungi, dinoflagellates, jellyfish, squid, echinoderms (starfish), cordates (worms), molluscs, arthropods (crabs and shrimp), fish (near-surface or deep-sea), beetles, and fireflies (Halsey3 181).
		Bioluminescence is a prevalent property of deep-sea fish and other organisms: it has been discovered that more than 70.0% of species in the deep sea produce light to compensate for the lack of sunlight they cannot receive in the deep water (22).
		The application of bioluminescence in living organisms is believed to be based upon four general uses: defense, offense, mating and courtship, and communication (22).

	Bioluminescence
		Bioluminescence is the light put out by a creature like a lightning bug or anglerfish; it's light produced and emitted as a result of a chemical reaction to convert chemical energy into light energy.
