The walrus feeds mostly on bottom dwelling shellfish, such as clams, cockles and mussels. After weaned, the baby walrus eats crustaceans, such as shrimp. The young
can not swallow large objects. The walrus uncovers the food from under the sand by squirting at the sand with water from its mouth. It also uses its large tusks to
uncover the food.
The walrus reaches sexual maturity when it is 6 years of age. When ready to mate, the male walrus does a very large display in front of the female to prove himself the
strongest bull. This display consists of whistles, barks, and growls. Many males show off, while the female chooses one. The cow usually tries to pick the largest and the
one who makes the loudest and most impressive display. When mates are chosen, the pairs go off together. Some of the bulls do not choose mates, and try to mate with
the cows that already have a bull. The original bull fights off the other, by using its tusks to hit it. Walrus mate on the pack ice.
The female carries its young for 15 months. It gives birth around early April or May. The infant is about 50 inches long. The calf stops nursing in 18 months. The mother
teaches it to swim by giving it piggy-back rides.
The walrus spends all of its life on ice floes, or the rocky shore not far away. Since the walrus lives in a place where the weather can be below subfreezing, it has a
thick coat of blubber around it. Walrus can range from the seas of Alaska, to the coasts of the Soviet Union.
