what is the definition of bioluminescence
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, as well as in some fungi, microorganisms including some bioluminescent bacteria and terrestrial invertebrates such as fireflies.In some animals, the light is produced by symbiotic organisms such as Vibrio bacteria.ioluminescence is a form of chemiluminescence where light energy is released by a chemical reaction. Fireflies, anglerfish, and other organisms produce the light-emitting pigment luciferin and the enzyme luciferase. Luciferin reacts with oxygen to create light:
