Puerto Rico is home to three bioluminescent bays, protected inlets that hold millions of marine bioluminescent dinoflagellates. These bays are huge tourist attractions, and swimming in them, when permitted, is popular. Often the visitors have sprayed themselves with insect repellants containing the active ingredient DEET. The purpose of this paper is to examine the effects of DEET on the ability of the dinoflagellates to emit light.
