Artic Fox
			Phylum: Class: Order: Family: Species: Chordata Mammalia Carnivora Canidae Alopex lagopus

The Arctic fox is similar to the red fox, but is smaller, having smaller ears in which to help retain heat. It lives in the tundra regions of Europe, Asia, North America and Greenland.

In the winter its thick white coat provides it with insulation and camouflage in the snow. In the summer its coat changes color to a grayish yellow, but remains white underneath. Hairs on the soles of its feet give the fox a good grip on snow and ice.
Arctic fox live in small groups and eat a wide variety of foods. In the winter, food is hard to find and they follow polar bears to take advantage of any uneaten seal meat. In summer, food is more abundant. They catch birds such as gulls and ducks, and mammals, such as voles and hares. In Europe, lemmings are the main source of food for the Arctic fox, and the population of fox rises and falls with the concurrent rise and fall of lemming populations.

Breeding begins in April and 5 to 8 cubs are born between May and June. When lemmings are abundant, as many as 20 cubs may be born in the same litter. A second litter is born in July or August.
