Dinoflagellates are single-celled organisms that flash on contact and shine their brightest at night after a bright sunny day. A tablespoon of water from Mosquito Bay in Puerto Rico can contain as many as 2,000 cells of the dinoflagellate Pyrodinium bahamense, or “whirling fire creature of the Bahamas.”
