Bioluminescence occurs when living organisms produce light through a chemical reaction. This reaction typically involves a light-emitting molecule called luciferin, an enzyme called luciferase, oxygen, and sometimes other molecules like ATP. The exact mechanisms can vary among organisms, but generally, the reaction produces light without generating significant heat, making it efficient for signaling, attracting prey, or camouflage in deep-sea environments. Many marine organisms like fireflies, jellyfish, and certain types of bacteria exhibit bioluminescence.
