Heterocapsa pygmaea (scanning electron micrograph)

Heterocapsa is a single-cell organism belonging to a group of algae called dinoflagellates. Heterocapsa is found year-round in Florida’s estuarine and coastal waters. Large concentrations, called blooms, can discolor the water red to brown and cause fish kills by depleting dissolved oxygen. Although blooms of Heterocapsa have killed bivalve shellfish in other parts of the world, adverse impacts from Heterocapsa have not been reported in Florida waters.
