A walrus is a marine mammal belonging to the family Odobenidae. Known for their distinctive tusks, whiskers, and hefty bodies, walruses are primarily found in the Arctic regions of the Northern Hemisphere. They exhibit a social nature and often haul out on ice or beaches in large groups. Walruses are known to feed primarily on benthic invertebrates, using their sensitive whiskers to find prey on the ocean floor. Additionally, they are well-adapted to their cold environment, with a thick layer of blubber that provides insulation against freezing temperatures in their habitat.
