Puerto Mosquito is a deep inlet in the cliffed southern coast of Vieques Island. The most important element of the fauna that gives the bay uniqueness is the high permanent concentrations of dinoflagellates, in particular the luminescent Pyrodinium bahamanse. The bay has the highest concentrations of bioluminescent dinoflagellates of the three luminescent bays in Puerto Rico and is considered the best example of a bioluminescent bay in the United States.
