Adult arctic foxes are usually between 28 and 41 inches in length. They weigh between 3 and 21 pounds, making them one of the larger carnivores in their environment. As of 2014, they live in the tundra and coastal areas of Alaska but are also found in Northern Canada, Europe and the Aleutian Islands. They primarily prey on lemmings but also eat eggs, insects, small birds and berries. They are able to survive in freezing environments because of their thick fur and small, compact bodies, which are easier to keep warm.
There are two types of arctic foxes, each with fur color that changes based on the season. Blue arctic foxes are dark gray in the summer and almost look brown. In the winter, their fur is blue-gray. White arctic foxes are brown and gray in the summer but white in the winter. White arctic foxes are more common in the tundra, and their white fur provides natural camouflage in the winter.Learn more about Mammals
