What causes bio-luminescence in ocean water?

Bioluminescence in ocean water is primarily caused by certain microorganisms, such as dinoflagellates and some species of bacteria, which produce light through biochemical reactions. These organisms contain luciferin, a light-emitting compound, and enzymes called luciferases that facilitate the reaction. Environmental factors like movement in the water, stress, or predation can trigger these organisms to emit light, creating stunning displays often seen in waves or when disturbed. This phenomenon serves various purposes, including attracting mates, deterring predators, or luring prey.
