Bioluminescent Bay (often called Bio Bay) is Puerto Rico’s key tourist destinations. The water luminescence is triggered by dinoflagellates, oceanic plankton which is able to generate an emerald green and ultramarine illumination when water is physically disturbed. Dinoflagellates are incredibly delicate microorganisms and are very sensible to the environment conditions such as balance of salt in the water, local climate, deepness of lagoon, air and water pollution, etc. Each one of these the aspects make bio bay a one of a kind, vulnerable ecosystem.
