The walrus has played a prominent role in the cultures of many indigenous Arctic peoples, who have hunted it for meat, fat, skin, tusks, and bone. The Atlantic walrus can be about 8 feet long and 2,000 pounds, while the Pacific walrus is larger, averaging about 10 feet long, with individuals topping 14 feet long and around 4,000 pounds. Walruses can use their tusks to help haul themselves up onto the ice, which is likely where this reference came from. Why Do Wolves Eyes Appear Red? The walrus palate is uniquely vaulted, enabling effective suction. As more walruses haul out on land instead of sea ice, nearshore prey populations will be subjected to greater predation pressure. To prevent oxygen loss underwater, walruses can store oxygen in their blood and muscles when they dive. Seals, Sea Lions, and Walruses | Smithsonian Ocean They use them to haul their enormous bodies out of frigid.

Like sea lions, walruses can rotate their hind flippers under their pelvic girdle, enabling them to walk on all fours. [60], Even though walruses can dive to depths beyond 500 meters, they spend most of their time in shallow waters (and the nearby ice floes) hunting for food.
