Bioluminescence is the ability of some living things to emit their own light.
Most animals that have bioluminescence live in the sea, such as jellyfish, fish, plankton, and crustaceans.
There are also some land insects that have bioluminescence, such as grasshoppers and lamp beetles.
Light emitted by Bioluminescence can be green, blue, yellow, or red.
Living creatures use bioluminescence as a way to attract partners, attract prey, or as a form of self -defense.
Some species of jellyfish can emit very bright light so that it can make the water around it glow.
Plankton which has bioluminescence can form natural phenomena called sea glow when the numbers are very large.
There are also several types of bacteria that have bioluminescence, such as Vibrio Fischeri who live in the intestine of the squid.
Bioluminescence is also used in medical research, such as to track cancer cells in the human body.
Some species of deep sea fish that have bioluminescence can make very bright light so that it can attract the attention of submarines or aircraft that pass over the sea.
