@traveltrademaldives: Ever seen a glowing beach full of neon blue dots, mimicking the starry sky? Locally called as 'Redhan lun' happens when a plankton, named as dinoflagellates, which does the trick. Scientists have only recently discovered that the plankton which lights up, does so with a chemical called luciferin and lights up only when agitated. It is believed that bioluminescence is used as a defense mechanism to draw predators towards the creature trying to eat the plankton. The tiny flashes of light are also supposed to disorientate and surprise the predator. #VisitMaldives #maldivesvirtualtour #maldivesgetaways #redhan #bioluminescence
