Walruses [Odobenus]

Description

Odobenus is the sole genus within the family Odobenidae, which includes the modern walrus (Odobenus rosmarus) as its only living member. This genus is characterized by its large size, distinctive tusks, lack of external ear flaps, and a thick layer of blubber. Walruses are primarily found in the Arctic Circle, inhabiting icy marine environments. They are highly sociable, often forming large herds on land or ice surfaces. Their diet mainly consists of benthic bivalve mollusks, which they locate with their sensitive whiskers and excavate from the ocean floor. The genus Odobenus is notable for its role in Arctic ecosystems, both as a predator and as a species impacted by changing ice conditions due to climate change.
