Polykrikos kofoidii

Polykrikos kofoidii is a species of phagotrophic marine pseudocolonial dinoflagellates that can capture and engulf other protist prey, including the toxic dinoflagellate, Alexandrium tamarense.^[3][4] P. kofoidii is of scientific interest due to its status as a predator of other dinoflagellates, a behavior that is significant in the control of algal blooms.^[5][6][7] It has a complex life cycle of both vegetative (asexual) and sexual reproduction complicated by its pseudocolonial structure.^[8]
