Seals and Walrus
Fur Seals make up one of the two distinct groups of mammals called “seals". Both the fur seals and the true seals are members of the Pinnipedia, which is usually regarded as a suborder of the order Carnivora but sometimes as an independent order. However, the fur seals, like their close relatives the sea lions, retain some ability to walk on land as their hind limbs can be brought forward under the body to bear the animal’s weight, and retain small but visible external ears.
