Odobenidae

The family Odobenidae is a small group of marine mammals, closely related to seals, that are characterized by their thick skin, a layer of blubber, and prominent tusks. The only living member of this family is the walrus (Odobenus rosmarus), found in Arctic seas. There are two subspecies: the Atlantic walrus and the Pacific walrus, with males being larger and possessing longer tusks than females. These tusks, which are enlarged upper canine teeth, are primarily used for mating displays and defense, not for digging food. Walruses feed on clams and mussels from the ocean floor and are gregarious animals that live in groups. They can move on land using all four flippers and have a gestation period of 15–16 months, typically giving birth to a single pup.12
