Biolumiscene refers to the phenomenon of bioluminescence, where living organisms produce light through biochemical reactions. This natural light emission can be found in various organisms, including certain species of bacteria, fungi, and marine animals like jellyfish and deep-sea fish. Bioluminescence serves various ecological purposes, such as attracting mates, luring prey, and deterring predators. The study of bioluminescence has applications in fields like biotechnology and environmental monitoring.
