The Clade Pinnipeds are typically recognized as ‘seasl’ and comprise of three families: the Odobenidae which only has Walrus, the Phocidae also known as ‘true seals’ because of the absence of ears, and the Otariidae also known as ‘eared seals’ because of the presence of ears which differentiate this family from the Phocidae. The Northern fur seal was named ‘sea ears’ by the Europeans that is quite evident from their scientific name Callorhinus ursinus which implies ‘bear like’. Discovered in the Northern Pacific, their geographical distribution is reasonably vast, but the population of this species is gradually declining because the northern fur seals are being hunted for their exotic fur. Although the northern fur seals have been consumed by the native Alaskan people yet their population did not decline as much as it did after the European arrived and began trading. Today the northern fur seals come under the category of Vulnerable species according to the IUCN.
