Dinoflagellata). They are characterized by a transverse flagellum that
encircles the body (often in a groove known as the cingulum) and a longitudinal
flagellum oriented perpendicular to the transverse flagellum. This imparts a
distinctive spiral to their swimming motion. Both flagella are inserted at the
