All about Bioluminescence
Bioluminescence is light that is made inside a living thing. It happens when a chemical reaction releases energy as light instead of heat. Many deep-sea animals, such as some fish and jellyfish, use this glow to hunt, hide or call to others.
Fireflies are one of the best-known land animals with bioluminescence. Some fungi also glow in dark forests. Scientists study these glows to learn new ways to make light and track cells in the body.
