Natural Phenomenon in Mayaro, Trinidad. Happens once every decade! The nearby river Ortoire is populated by bioluminescent plankton and glows once stressed. It spills into the coast of Mayaro and turns the beach's shore into this! Most amazing part is that this has been occurring for over 80years and the locals have kept it a secret in order to protect it! Miracles on earth....Beautiful twin islands of Trinidad&Tobago.
