Polar fox

A polar fox looks differently in summer and in winter. In winter the polar fox has a thick and long hair, and it seems to be completely round, its ears just emerge from the fur. In the short summer the polar fox fur becomes sparse, and for this reason it seems to be slender and its ears seem to be very big.

The polar fox lives in the tundra. It eats everything it finds. Most often it catch mice but can catch as well a bird or a fish, it picks up berries, various herbs. The polar fox often accompanies white bears and obtains a part of flesh of their prey. If the fodder is abundant, the polar fox makes stocks. It pushes them in between stones or buries them in the ground.

In summer, a subcutaneous layer of fat is accumulated for protecting it against cold. The polar foxes dig burrows with many entries. They form stable families.
