Walruses are seals that live in the Arctic seas of the Earth's northern hemisphere. They are predators and primarily prey on mussels. Walruses are famous for their big, long tusks. Yet, they are not able to catch their prey with them. The tusks are just too big and impractical for this.

Why Does a Walruses Have Tusks?

With their tusks walruses defend themselves against hungry polar bears. In most cases the polar bear is the loser of the battle and often fatally wounded. Yet, the walruses use their teeth mainly to heave their bodies from the water onto ice floes or rocks. If there is no hole in the icy surface, the tusks can be used just like an ice-pick. By the way: The boss of the walrus community is the one with the biggest tusks!

Walrus or Polar Bear – Which One is Bigger and Heavier?

With a weight of approximately 1,984 lb (900 kg), the Polar bear is too heavy for any weighing scale. The walrus weighs even more: A grown-up male walrus can get heavier than 3,300 lb (1,500 kg). The walrus is also bigger. While it can grow 12.4 ft (3.8 m) in length, the Polar bear is no more than 10 ft (3.1 m) long.

Walruses Love Mussels to Bits

Walruses really like mussels by the way. In order to get at the delicious meat, they press their lips against the shell and suck it out. One meal consists of 3,000 to 6,000 mussels!

Walruses Use Their Whiskers to Locate Prey

When they are hunting, they use their (up to 450!) whiskers on their snouts to detect prey in the water. They blow at their victims to make them move and then catch them. 

How Do Walruses Survive in Arctic?

Walruses spend more than two thirds of their lifetime dabbling in the water. In order not to freeze to death at icy temperatures, they have a layer of fat, which is up to 15 cm thick. During the winter it accounts for about one third of the walrus’s total weight.
