What is the adaptive significance of bioluminescence in a dinoflagellate?

Bioluminescence in dinoflagellates serves several adaptive purposes, primarily related to survival and predator avoidance. When disturbed, these organisms emit light, which can startle or confuse predators, allowing them to escape. Additionally, the light may attract larger predators that feed on their attackers, thereby reducing predation risk. This phenomenon also plays a role in communication and potentially in reproduction, enhancing their overall fitness in various marine ecosystems.
