Photophores are organs that are used by fish (and invertebrates) to produce light either by chemical reaction or through symbiotic bacteria capable of bioluminescence. Most fish that use photophores live in the deep sea where light from the surface is limited. Like a firefly in the sea, some of these fish use photophores to attract … [Read more…]
Bioluminescence is a chemical process by which some fish species can produce their own source of light. They have light producing organs known as photophores. The light is emitted from specialized cells called photocytes or from symbiotic fluorescent bacteria that are cultured by the fish in photophores. Most fish bioluminescence is blue (because blue-green light transmits … [Read more…]
