Bioluminescence

Definition

Bioluminescence is the natural phenomenon where living organisms produce and emit light, often through biochemical reactions involving luciferin and luciferase. This unique trait is commonly found in various marine species, certain fungi, and some terrestrial insects. Bioluminescence serves various ecological purposes such as attracting mates, deterring predators, and luring prey, making it a fascinating subject in fields like biosensor design and drug discovery.
