Walrus front flipper. Close-up of a front flipper of an Atlantic walrus (Odobenus rosmarus). This marine mammal uses its front (pectoral) flippers for steering when swimming, and uses them together with its hind flippers for walking when on ice or land. The skin on the flippers is thick, giving good traction. The front flippers have five digits, each with a small claw. In contrast with the longer and triangular rear flippers (used for propulsion, see C026/2361), the front flippers are shorter and squarer in shape. Photographed in spring in Greenland.
