Walrus

Walrus is a large flippered marine mammal with a discontinuous distribution about the North Pole in the Arctic Ocean and subarctic seas of the Northern Hemisphere. The walrus is the only living species in the family Odobenidae and genus Odobenus. This species is subdivided into three subspecies: the Atlantic walrus (O. rosmarus rosmarus) which lives in the Atlantic Ocean, the Pacific walrus (O. rosmarus divergens) which lives in the Pacific Ocean, and O. rosmarus laptevi, which lives in the Laptev Sea of the Arctic Ocean.

Physical Characteristics[edit | edit source]

Walruses are easily recognized by their prominent tusks, whiskers, and bulkiness. Adult males in the Pacific can weigh more than 2,000 kg (4,400 lb) and, among pinnipeds, are exceeded in size only by the two species of elephant seals. Walruses live mostly in shallow waters above the continental shelves, spending significant amounts of their lives on the sea ice looking for benthic bivalve mollusks to eat.

Behavior[edit | edit source]

Walruses are relatively long-lived, social animals, and they are considered to be a "keystone species" in the Arctic marine regions. The walrus has played a prominent role in the cultures of many indigenous Arctic peoples, who have hunted the walrus for its meat, fat, skin, tusks, and bone.

Conservation[edit | edit source]

Due to the global warming, the sea ice has been melting, which is a threat to the walrus population as they rely on the sea ice while giving birth and changing their locations. Several nations have enacted various protective measures for the walrus population.
