Smaller than common fox, polar fox lives in north hemisphere’s arctic areas. Grey in the summer, white in winter are good camouflages for each season. Its fur helps it keep the warm and its feet are covered with thick hairs. The tail protects the rest of the legs and the muzzle when the fox is sleeping. Cold weather is rarely a problem for polar foxes. Its alimentation varies between bigger animals’ old carcass, in winter, and preys such as birds, fish, rodents, other little mammals, in summer.

In northern Europe (Norway, Sweden, and Finland), the specie is endangered: Only 120 adults are still alive in the 3 countries and the number varies depending on the number of lemmings, one of their preys.
