Bioluminescence is the production and emission of light by living organisms, such as certain types of fish, insects, and marine animals. This phenomenon occurs when chemical reactions within the organism generate light energy instead of heat. Specialized cells called photophores contain light-emitting molecules, such as luciferin and luciferase, which react together to produce light. Bioluminescence serves various purposes in nature, including attracting prey, communicating with other organisms, and camouflage.
