Presentation Transcript

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

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

  3. 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

  4. Some of the molecules

  5. Purpose of Bioluminescence • It can light the way to find food (flashlight fish)‏ • Attract prey (angler fish, viper fish)‏

  6. Purpose of Bioluminescence (continued)‏ • It can be used to attract a mate (the loosejaw fish uses light in its cheeks

  7. Purpose of Bioluminescence (continued)‏ • It can use bioluminescence for protection (deep sea shrimp project light into the approaching predator, temporarily blinding it)‏
