TRANSCRIPT

  • 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)
