Arctocephalus philippii (Juan Fernández Fur Seal)

Wikipedia Abstract

The Juan Fernandez fur seal is part of the group of eared seals. Fur seals in general have thick insulating fur that protects the skin from cold water, they have small ear flaps on the side of their head, and they hold their weight on their front flippers which are also used for land locomotion. Fur seals are different from true seals because they have the external ear flaps, but also true seals use their chest for support and movement, fur seals walk on their front flippers.
