Bioluminescent bacteria are light-producing bacteria that are predominantly present in sea water, marine sediments, the surface of decomposing fish and in the gut of marine animals. While not as common, bacterial bioluminescence is also found in terrestrial and freshwater bacteria. [ 1 ]
Luminescent bacteria emit light as the result of a chemical reaction during which chemical energy is converted to light energy. Luminescent bacteria exist as symbiotic organisms carried within a larger organism, such as many deep sea organisms, including the Lantern Fish, the Angler fish, certain jellyfish, certain clams and the Gulper eel.
Bioluminescence is the production of light by living organisms. This list of bioluminescent organisms is organized by the environment, covering terrestrial, marine, and microorganisms. Terrestrial animals
Bioluminescence is a chemical reaction regulated by a gene or bacteria that enables living organisms to produce light naturally. Over 90 percent of marine organisms are bioluminescent -- algae ...
Small extracellularly secreted molecules stimulate the bacteria to turn on genes for light production when cell density, measured by concentration of the secreted molecules, is high. [34] Pyrosomes are colonial tunicates and each zooid has a pair of luminescent organs on either side of the inlet siphon. When stimulated by light, these turn on ...
Some 95% of the light-producing bacteria are voided at dawn every morning; the population in the light organ then builds up slowly during the day to a maximum of some 10 12 bacteria by nightfall: this species hides in sand away from predators during the day, and does not attempt counter-illumination during daylight, which would in any case ...

In the process of colonization, ciliated cells within the animals' photophores (light-producing organs) selectively draw in the symbiotic bacteria. These cells create microcurrents that, when combined with mucus, [ 16 ] promote the growth of the symbionts and actively reject any competitors.
