Sluuuurp!

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.

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.

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!

What is the Use of the Long 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!

What Do Walruses and Trees have in Common?

You can easily tell the age of a tree by counting its growth rings. It is quite similar with walruses: Their teeth also contain “growth rings”.

Run Away From a Walrus? Have a Try!

Walruses might appear rather plump when they are moving on all fours across the shore. Yet, they can move as quickly as a human being.

Walrus or Elephant – Which Animal is Heavier?

With a weight of approximately 1,984 lb (900 kg), the polar bear is too heavy for any weighing scale. But the walrus weighs even more: A grown-up male walrus can get heavier than 3,306 lb (1,500 kg).

Splish Splash!

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.

Reproduction: Slow and Steady Wins the Race

Walruses take their time. Their pregnancy lasts 11 months and they never give birth to more than one calf. Twin births are very rare.
