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. 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 Northern fur seal or Callorhinus ursinus fur 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.

The Northern fur seal or Callorhinus ursinus teeth are sharp, conical and mostly single-rooted, as is common with carnivorous marine mammals adapted to tearing fish flesh. The upper canines are prominent.

Northern fur seal or Callorhinus ursinus are built for efficient terrestrial locomotion. Their hind limbs are in a plantigrade stance and are able to rotate under the body for quadrupedal locomotion and support.

When swimming, there are two different types of movement: locomotion and diving. These seals swim primarily with forelimb propulsion due to their physiology. Northern fur seal or Callorhinus ursinus have flexible joints between vertebrae for better maneuverability in the water as well as “greater muscular leverage” for pectoral strokes.

Stroke patterns are different for different dive types and locomotion, and stroke rates vary for individuals since there’s a relationship between maximum stroke rate and body size.

International Seal Day - March 22nd

Every year on March 22nd, the International Day of the Seal promotes the conservation of seals worldwide. It’s also a day to celebrate this amazing marine mammal.

A seal is a type of animal called a pinniped, which is Latin for “fin-footed.” Other pinnipeds include the walrus and sea lion. What makes seals different than other pinnipeds is that they don’t really use their flippers to walk. When on land, they usually slide around on their bellies. In the water, their flippers help them swim really fast. Seals are also much quieter and smaller than their sea lion and walrus cousins.
