Description:

The scientific name of the walrus, Odobenus rosmarus, means "tooth-walker." This refers to the two most noticeable characteristics of the walrus--the elongated tusks, and the ability to walk on land using flippers. The walrus is the only living member of the Pinniped family (seals, sea lions, and walruses) with external tusks.

Both male and female walruses are red-brown in color, but the females have a thicker coat of hair than the males. Both genders have thick skin (over two inches thick on the neck of a male walrus) and a layer of heavy blubber to keep them warm. All walruses have an air sac in the throat. A walrus can inflate its air sac to help keep its head afloat while swimming.

The tusks of the walrus are elongated teeth, up to three feet in length. Those of the male are slightly longer than those of the female and are more likely to be broken or worn down. That’s because males use their tusks in dominance battles to establish their social standing within the group. Females do not use their tusks for dominance, but do use them to climb out of the water and to break breathing holes in the ice. In addition to its tusks, an adult walrus has sixteen other, shorter teeth.

The walrus is not a small animal. Generally, adult walruses are 14 feet long and can weigh up to 2,000 pounds. They have two pairs of flippers. In the water, the front flippers act as stabilizers and the rear flippers provide propulsion. When the walrus is on land, the hind flippers can be rotated and used for walking.

Although prehistoric members of the walrus family lived throughout the world’s oceans, modern walruses are found near pack ice in circumarctic waters. During most of the year, large groups of hundreds of walruses live on and around the Arctic pack ice. During summer and early autumn, these groups gather on beaches for the breeding season. North Pacific walruses often migrate by riding on cakes of ice as the pack ice breaks up in the summer.

Walruses are benthic (or bottom) feeders. Walruses use colorless whiskers called vibrissae to search the ocean floor for clams, which they suck out of their shells and consume. They will also eat slow-moving fish, snails, worms, mussels, sea cucumbers, soft-shelled crabs, and shrimp. A walrus can hold its breath for up to ten minutes while it dives for its food. Although most walruses do not attack other marine mammals, a few will attack seals and small whales.

Walrus pups are born in the spring, after a fifteen month gestation period. Walrus mothers are very attentive, suckling their pups for the first two years of life. The mother is also constantly alert for danger to her offspring, carrying them on her back, or even grabbing the pup with her flippers and diving beneath the surface when danger is near. Walruses (and especially their pups) are hunted by killer whales, polar bears and humans. Unlike many other marine mammals, walruses seem to thrive in captivity. They can live for over forty years, and have been known to breed in captivity as well.
