ABSTRACT
This is the first record of the dinoflagellate Lingulodinium polyedrum in a red tide bloom in the North Pacific coast of Costa Rica. The sample was collected on April 2000 at Culebra Bay, Gulf of Papagayo, from a patch of aproximatly 2000 m2, which produced a red discoloration of the water and a peculiar strong odor. This species produces spherical hypnocysts that may remain for decades when dark or anoxic conditions are present; L. polyedrum had been associated with the production of paralyzing toxins such as saxitoxins and yessotoxins. A second smaller patch was observed close Panama beach, into the bay, where we found seven puffer fish (Diodontidae) and two lobsters dead in the sand. It is important to develop a monitoring program to identify seasonal behavior of this species and ameliorate its impact on coastal human communities.
