Now Playing As: Captioned (English) (change)

Bioluminescence is a chemical process that allows living things to produce light. On land, fireflies are one of the most visible users of bioluminescence. In the ocean, bioluminescent creatures can be found from the surface all the way down to the deep sea floor. Scientists are still trying to figure out why and how animals adapted this feature.
