They have a short, straight caudal spine unlike the characteristically looped caudal spine of parthenogenically-produced individuals (Simm and Ojaveer, 1999). It is not known, therefore, whether Cercopagis will ultimately be an energetic source or sink in the Great Lakes. The “resting eggs” of this water flea can be transported long distances, and can even survive cold winters on the sea bed, hatching only when the water is warmer and food is available.
