Flashlight fish, also called lantern-eye fish, are among the few species of non-deep-sea fishes to possess such organs. Bioluminescent bacteria create the light continuously, but each species has its own mechanism for decreasing the luminescence; when swimming, some fishes create a blinking effect by alternately covering and uncovering the light. They use this light in a rather brilliant way to confuse and distract predators, and also to attract food. They even use it to communicate!
