The light is the dinoflagellate Pyrodinium bahamense, a single-celled plankton whose luciferin reaction fires as a defense when the water around it moves: a swimmer's stroke, a hull's wake, a hand dipped off a boat's gunwale.","Evening boat tours run from the village malecón into the glow, which is strongest on moonless nights. The dossier's research notes hold one honest snag: the tourism guide that sources the file contradicts itself about whether swimming is permitted, so the record asserts neither permission nor restriction pending the regulator's word."]},{"heading":"An explained light","paragraphs":["La Parguera is one of Puerto Rico's three bioluminescent waters, with Laguna Grande at Fajardo and Vieques's Mosquito Bay, and its mystery is fully solved — bioluminescence, not specter.
