The Family Odobenidae consists of a single living species, the walrus (Odobenus rosmarus), a large marine mammal found in Arctic and sub-Arctic regions. Walruses are distinguished by their long tusks, whiskered faces, and thick blubber that insulates them in cold waters. They are social animals, often forming large herds on ice floes or beaches, and are primarily benthic feeders, using their sensitive whiskers and powerful suction to eat mollusks and other invertebrates from the seafloor. As apex predators and key components of Arctic ecosystems, walruses play important roles in structuring benthic communities and are culturally and economically significant to indigenous peoples.
