Bioluminescence is the production and emission of light by a living organism. It is a form of chemiluminescence. Bioluminescence occurs widely in marine vertebrates and invertebrates, in some fungi, microorganisms including some bioluminescent bacteria and terrestrial arthropods such as fireflies. In some species the luciferase requires other cofactors such as calcium or magnesium ions and also the energy-carrying molecule adenosine triphosphate. In evolution, luciferins vary little: one in particular, coelenterazine, is found in 11 different animal phyla, though in some of these, the animals obtain it through their diet.
