Volvox sp. performed diel vertical migrations in Lake Cahora Bassa, the amplitude of which greatly exceeded those reported for other species of freshwater algae. Migration velocities even exceeded the maxima attained by marine dinoflagellates. The daytime depth distribution is attributed to the light regime and the nighttime depth distribution to phosphorus uptake in deeper water layers.
