Has anyone seen Finding Nemo? I sure hope you have. If not, I highly suggest that you do. It is a fantastic movie and has quite a bit of Marine Science involved that is actually accurate. In one scene, Marlin (Nemo's dad) and Dori have fallen into this deep, benthic trench. They all of the sudden see a little twinkling light and begin to chase it. They soon find out that it is merely the bioluminescence of a fish that wanted to eat them. This fish was based on the Angler Fish and the Hatchet Fish. The Angler Fish has a small lure on its dorsal side which lights up. Bacteria that are located in this spot are what create the light. The light attracts prey close enough where it can catch it. In these dark areas of the ocean, organisms need all the help they can get. Bioluminescence is just one little trick they have evolved.
