However, an angry, wounded walrus can injure a hunter or damage a boat with its tusks. Walruses spend most of their time in herds. During the mating season, male walruses make unusual bell-like sounds underwater. Walruses are mammals. A female walrus usually has one calf every other year and cares for her young for about two years.
Twins are rare.
Some walruses live as long as 40 years. Traditionally, the Inuit used the walrus hides to make shelters or boats and burned the oil from walrus blubber for heat and light. The walrus is in the order Pinnipedia. It forms the walrus family, Odobenidae. Its scientific name is Odobenus rosmarus.
