Gymnodinium (Dinoflagellata) is the only genus of naked dinoflagellates found in Lake Kinneret. This genus never forms blooms but occurs quite often in small densities. Like other dinoflagellates, Gymnodinium has 2 unequal flagella, the longitudinal "whiplash" flagellum is seen in this picture, the second, transverse flagellum is hidden in the transverse groove, or cingulum.
