Why Do Some Animals Glow In the Dark?

Answer 1

Answer:

light is produced by a compound called luciferin, which releases light when it reacts with oxygen. All bioluminescent animals contain luciferin, but some (like tiny dinoflagellate plankton) produce their own, where others (like squid and some fish) absorb bacteria that contain luciferin.
