Odobenus rosmarus


They are found in the Arctic Ocean above Scandinavia, Greenland and Canada.


They live in the ocean or on pack ice (sheets of ice on the Arctic Ocean) or on rocky beaches.

Body Traits

Males can be 10 feet long and weigh more than a ton (about 2,600 pounds). Females are much smaller at about 8 feet long and 1,800 pounds. They have 6 inches of blubber to keep them warm in Arctic temperatures. Their flippers are like oars, making them slow but strong swimmers. They can be brown to rosy pink. Both males and females have tusks, though the male's tusks are longer.


They use their tusks to pull themselves along on land (they are sometimes called “toothwalkers”). Males sometimes use their tusks to fight for territory. They can dive very deep for food.


They eat shellfish, like clams and mussels.


Their most dangerous predator is man, but they are also killed by polar bears and killer whales. Pollution also kills walruses.
