Arctic Animal life
They are excellent swimmers, and the coldest water does not bother them. They just jump into any leads that open in the pack ice and swim across. They are quiet enough to sneak up on a sleeping seal and strong enough to kill it with one blow. They have a very strong sense of smell, which they use to find prey out on the ice. Polar bears live most of their lives out on the pack ice. Males go to the land only when the ice is gone. The females, however, will dig themselves into a den of snow on land for the winter. There, the mother bears have their cubs, usually twins. Bears usually eat fish, birds' eggs, seaweed, and dead whales, but they would rather have a meal of seal or walrus. The Arctic fox will often trail the bears onto the ice to eat their leftover food. The fox also eats rabbits, lemmings, and voles.
