Callorhinus is a genus of just one species (a “monotypic” genus) within the eared seal family of sixteen species -  Pribilof fur seal (also known as the Northern fur seal and Alaska fur seal).

The Pribilof fur seal (Scientific name: Callorhinus ursinus) is one of 16 species of marine mammals in the family of Eared seals which include sea lions and fur seals. Together with the families of true seals and Walruses, Eared seals form the group of marine mammals known as pinnipeds.

Eared seals differ from the true seals in having small external earflaps and hind flippers that can be turned to face forwards. Together with strong front flippers, this gives them extra mobility on land and an adult fur seal can move extremely fast across the beach if it has to. They also use their front flippers for swimming, whereas true seals use their hind flippers.

Like other Eared seals, the male Pribilof fur sealis considerably larger than the female.

Like other fur seals, the Pribilof fur seal was long hunted for its skin which almost led to the species extinction in the mid 1700s. All commercial hunting has ceased at sea and only limited numbers are now taken under license.
