The Northern fur seal or Callorhinus ursinus is an eared seal found along the north Pacific Ocean, the Bering Sea, and the Sea of Okhotsk.
It is the largest member of the fur seal subfamily (Arctocephalinae) and the only living species in the genus Callorhinus. A single fossil species, Callorhinus gilmorei, is known from the Pliocene of Japan and western North America.
Northern fur seal or Callorhinus ursinus have extreme sexual dimorphism, with males being 30 to 40 percent longer and more than 4.5 times heavier than adult females. The head is foreshortened in both sexes because of the very short, down-curved muzzle, and small nose, which extends slightly beyond the mouth in females and moderately in males.
The pelage is thick and luxuriant, with a dense underfur in a creamy color. The underfur is obscured by the longer guard hairs, although it is partially visible when the animals are wet. Features of both fore and hind flippers are unique and diagnostic of the species. Fur is absent on the top of the fore flippers and an abrupt clean line is seen across the wrist where the fur ends.
Callorhinus ursinus hind flippers are proportionately the longest in any otariid because of extremely long, cartilaginous extensions on all of the toes. Small claws are on digits 2 to 4, well back from the flap-like end of each digit.
The ear pinnae are long and conspicuous, and naked of dark fur at the tips in older animals. The mystacial vibrissae can be very long, and regularly extend beyond the ears.
The Northern fur seal or Callorhinus ursinus adults have all white vibrissae, juveniles and subadults have a mixture of white and black vibrissae, including some that have dark bases and white ends, and pups and yearlings have all black vibrissae.
The eyes are proportionately large and conspicuous, especially on females, sub-adults, and juveniles.
