Introduction
Emission of energy in the form of visible light duringchemical or biochemical processes is calledChemiluminescence (CL) or Bioluminescence (BL).
1 The energy released should be higher than that of theelectronically excited product or intermediate molecules.
2 The product must be a fluorecent molecule so that thetransformation of the excited molecule to the ground stateis accompanied by visible light emission, or the reactionmixture has to include energy acceptor molecules withfluorescent properties.

BL is the luminescence that occurs inor is derived from living organisms.The basis of BL is a CL reactioncatalyzed by a specific enzyme.The Quantum yields of BL reactionsusually lie between 0.1-0.9.All proteins catalysts of BL reactionsisolated are oxygenases(luciferin-luciferase or Photoproteins).

Luciferins-LuciferasePeer to peer, illuminating
Luciferins are a class of small-moleculesubstrate each for their correspondingprotein enzyme luciferase.
Luciferins are oxidized in the presence ofthe enzyme luciferase to produceoxyluciferin and energy in the form of light.
There are five general types of luciferins.
Luciferin and luciferase are not specificmolecules. They are generic terms for asubstrate and its associated enzyme (orprotein) that catalyze a light-producingreaction.

Cypridina BL.
Common in seawater and in the guts oforganisms. Also used in the lure ofAnglerfish and in the ventralcounterillumination of the bobtail squid(Euprymna scolopes) Most pelagiccrustacean groups (with the exception ofisopods) have luminous members. Theseinclude copepods, ostracods, amphipods,decapod shrimp and euphausiids (krill).Amazingly, three of the major marineluciferins are used in various crustaceans(ostracod-type luciferin,dinoflagellate-type luciferin,coelenterazine). Crustaceans are also themost likely source for coelenterazine inthe sea, as there is evidence that theycan produce it.

Dinoflagellate BL System.
If you see luminous sparkles in the wakeof a boat, or in splashing waves on thebeach, it is probably coming fromdinoflagellates. These single-celledprotists can be photosynthetic, or theymay be heterotrophic (eat otherorganisms), or some combination of thetwo. They may become very abundantduring red tides, and are thought to usetheir light as a burglar alarm to attractpredators to animals that are grazing onthem.

Conclusion
Bioluminescence is a very important physical phenomena untilnow not well understand but very common in underseaorganisms, some kind of mushrooms and insects.The physical knowledge of Bioluminescence can be importantfor ecological generation of light and like source of energy.
