Bioluminescence is the production and emission of light by living organisms. This phenomenon occurs through a chemical reaction that involves a light-emitting pigment called luciferin and an enzyme called luciferase. When luciferin reacts with oxygen in the presence of luciferase, it produces light without emitting heat, allowing organisms to glow in the dark. Bioluminescence is commonly observed in various marine organisms such as jellyfish, fish, and plankton, as well as some insects and fungi. It serves different purposes in nature, including attracting prey, confusing predators, communication, and camouflaging.
