bioluminescent algae

Bioluminescent algae are tiny, plant-like organisms that produce light through a chemical reaction within their cells. When disturbed, such as by waves or movement, they emit a glowing blue or greenish light, creating mesmerizing nighttime displays in oceans and lakes. This natural luminescence is a defense mechanism to deter predators or attract output organisms that help them reproduce. The most common bioluminescent algae are dinoflagellates, single-celled entities that play a vital role in marine ecosystems. Their glowing effect results from enzymes called luciferases acting on compounds called luciferins, producing light without heat.
