text: Dinoflagellates possess two flagella, one (the transverse flagellum) may be contained in a groove-like structure around the equator of the organism (the cingulum), providing forward motion and spin to the dinoflagellate, the other (the longitudinal flagellum) trailing behind providing little propulsive force, mainly acting as a rudder.
