Lantern fish

Lantern fishes) Myctophum Protomyctopbum, Diapbus, Benthosema, etc. 

The light emission continues until all of the luciferin has been oxidized. This type of reaction is found in fireflies, Cypridina, Latia, and many types of fish, such as lantern fish or hatchet fish.

Light plays a vital role in the life of all oceans. At the simplest level, it provides one of the basic requirements for photosynthesis and promotes development of a food chain. Some species of fish that live in the darker reaches of the oceans also rely on light for survival. Some of these species, such as lantern fish, have even developed their own artificial means of generating light.

There are many thousands of different species of luminescent organisms. Some are familiar, such as the firefly (and the larval form, the glowworm), lantern fish and the microscopic plankton responsible for the so-called phosphorescence of the sea. The great majority of organisms however inhabit the seas, many of them in the deepest parts. So widespread is the occurrence that it has been estimated that greater than 70% of all organisms below 400 m are luminescent [8].
