  2. What is Bioluminescence • When an organism emits light from its body • It can be voluntary (on purpose) • Or involuntary (not on purpose)

  11. Why use bioluminescence? • Warning to predators • Camouflage • Navigation • Communication • Finding mates • Attract prey • Angler fish

  12. Camouflage • Cookiecutter shark - Counterillumination. As this shark rises closer to the surface, it lights its underside so a predator looking up from beneath does not see its full silhouette. The shark “disappears”. Widder http://www.sciencenews.org/sn_arc98/8_1_98/fob5.htm

  13. Communication Attracting Mates • Atlantic midshipman http://public.gettysburg.edu

  14. Attract Prey • Angler fish---the lighted lure attracts prey. • Cookiecutter shark-Since only a small part of its body is easily visible, it looks like a smaller animal—attracting something that thinks it is going to get a meal, but instead becomes a meal for the much larger shark.
