Deep Sea Creatures

Many species of deep ocean fish have special adaptations to living in extremely high pressure, low light conditions. Some of them are black as night all over with light organs (called photophores) in strategic places on their bodies, including one on a long dorsal fin that serves as a lure for the fish it preys upon. Some don't have any pigment (color) at all - they're "see through", some have enlarged eyes, presumably for gathering as much light as possible where there is little or no light at all. The light organs create lights by using a chemical process called bioluminescence...
