Some animals have a fascinating ability called bioluminescence, which allows them to produce light from their bodies. This natural glow is caused by a chemical reaction inside their cells, often involving a substance called luciferin. Creatures like jellyfish, fireflies, certain types of squid, and deep-sea fish use this light to attract mates, hunt prey, or defend themselves by confusing predators.

Bioluminescence is especially common in the deep ocean, where sunlight can’t reach. In these dark environments, glowing helps animals communicate and survive in ways we are only beginning to understand. Scientists are studying these glowing creatures not only to learn more about life in extreme conditions but also to explore how bioluminescence could inspire medical and technological advancements in the future.
