The Northern Fur Seal, Callorhinus ursinus, is an eared seal. It is the only species in the genus Callorhinus. It is found in the north Pacific Ocean.

1 Physical description

The Northern Fur Seal, has substantial physical differences compared to its cousins: its head is smaller, snout shorter and the hindflippers are the largest of any eared seal. The "fingers" on the hindflippers are conspicous by their length. Males are substantially larger (2m, 270kg) and darker-coloured (the pelage is dark brown or black) than the female (1.5m, 60kg, light brown to grey). Males live for up to 20 years, and females 25.

Northern Fur breeding grounds are fairly densely packed, though activities at sea are generally solitary. Pups are wean ed in October. They enter the water and start heading south towards the end of November. Individuals return to the breeding grounds in May. Males aggressively establish their territory and herd females into it. Males are polygynous with each breeding season. June is birthing month. Having said with their pups for the first eight to ten days of their life, females then begin foraging trips lasting about a week. These trips last for about four months before weaning.

Fur Seals eat a mixture of pelagic fish and squid.

2 Range

The Northern Fur Seal is found in the north Pacific - its southernmost reach is a line that runs roughly from the southern tip of Japan to the southern tip of Baja California, the Sea of Okhotsk and the Bering Sea. The largest breeding colonies are the Pribilof Islands and Commander Islands in the Bering Sea. Breeding also occcurs on Robben IslandRobben Island ( Dutch for "seal island") is an island 12 km off the coast of Cape Town, South Africa. It was first inhabited thousands of years ago when the channel dividing it from the mainland was not under water.

There are estimated to be around 1.2m Northern Fur Seals across the range. The other fur seal found in the northern hemisphere is the Guadalupe Fur SealThe Guadalupe Fur Seal Arctocephalus townsendi is a fur seal. It is one of six members of the Arcetocephalus genus, but the only one to be found in the Northern Hemisphere. Sealers reduced the population to just a few dozen by the late-nighteenth century - the two species' ranges overlap in the north-east Pacific.
