Watch Bioluminescent Plankton in Koh Phi Phi

Bioluminescent plankton is a captivating natural phenomenon that occurs when certain species of plankton emit light in the dark. This mesmerizing display is caused by a chemical reaction within the plankton's cells, resulting in them lighting up underwater. The bioluminescence is a defense mechanism for some species, as the sudden burst of light startles predators, allowing the plankton to escape.
