Which Puerto Rican bay is officially recognized as the brightest bioluminescent bay in the world?
Tap your pick
Mosquito Bay, located on the island of Vieques, holds the Guinness World Record for its incredible bioluminescence. The glow is caused by microscopic organisms called dinoflagellates, which light up when disturbed. Amazingly, a single gallon of this water can contain over 700,000 of these tiny organisms!
