Marine BioluminescenceA variety of sea creatures produce light by a variety of chemistries.Bioluminescence serves many purposes in the marine environment.
VarietyMicroscopic: Bacteria, dinoflagellates, RadiolariansAnthozoa: Sea fans, Soft corals, Sea pens, Sea psansiesMolluscs: Sea slugs, Boring bivalves, Cuttlefish, Squid,Vampire squid, Octopods
Variety (continued)Arthropods: Copepods, Ostracods Malacostraca, Opossum shrimp, Amphipods, Euphausiids (Krill), Decapod shrimpHemichordates (Acorn worms)Chordates Tunicates: Sea squirts; Pyrosomes (Fire cylinders); LarvaceansVertebrates:Sharks, Anchovies, Gulper eels
Some of the molecules
Purpose of BioluminescenceIt can light the way to find food (flashlight fish)Attract prey (angler fish, viper fish)
Purpose of Bioluminescence (continued)It can be used to attract a mate (the loosejaw fish uses light in its cheeks
Purpose of Bioluminescence (continued)It can use bioluminescence for protection (deep sea shrimp project light into the approaching predator, temporarily blinding it)
