The aquatic and terrestrial locomotion of the walrus are described using the frame-by-frame analysis of 16 mm cine film and the manipulation of bone-muscle preparations. The

hind limbs of the walrus are the major source of aquatic propulsion; the forelimbs are used for manoeuvring as well as for propulsion.
