Presentation transcript:

Marine Bioluminescence A variety of sea creatures produce light by a variety of chemistries. Bioluminescence serves many purposes in the marine environment.

Variety Microscopic: Bacteria, dinoflagellates, Radiolarians Anthozoa: Sea fans, Soft corals, Sea pens, Sea psansies Molluscs: Sea slugs, Boring bivalves, Cuttlefish, Squid,Vampire squid, Octopods

Variety (continued)‏ Arthropods: Copepods, Ostracods Malacostraca, Opossum shrimp, Amphipods, Euphausiids (Krill), Decapod shrimp Hemichordates (Acorn worms)‏ Chordates Tunicates: Sea squirts; Pyrosomes (Fire cylinders); Larvaceans Vertebrates:Sharks, Anchovies, Gulper eels

Some of the molecules

Purpose of Bioluminescence It can light the way to find foo d (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)‏
