Biolumiscence is a reaction that causes organisms to light up after being disturbed, or being
attacked in general. There are different kinds of Biolumiscence that both living organisms have on land and
sea. Some minerals also have a phosphorescence which is a light up for rocks. Deep sea animals use this
bioluminescence for self defense. The light will confuse whatever predator is attacking.
The picture above is a lantern fish. It is also the same fish from "Finding Nemo" that was attacking Marlin and
Dory when they dropped the goggles into the deep ocean. This fish uses Bioluminescence as a night light so
they can see their prey and their predators.
