Check out our shiny new story-based merch at null Most animals on earth are bioluminescent, but almost all of them live in the ocean - and scientists aren’t sure why. LEARN MORE ************** To learn more about this topic, start your googling with these keywords: - Bioluminescence: the biochemical emission of light by living organisms such as fireflies and deep-sea fishes. - Biofluorescence: The emission of previously absorbed light by fluorescent proteins in a living organism. - Luciferin: an organic substance, present in luminescent organisms such as fireflies, that produces light when oxidized by the action of the enzyme luciferase.
