Wolves were formerly circumpolar, originally found in all Arctic habitats south through all temperate non-tropical habitats. Current: In North America, they are now found only in Alaska and Canada and isolated pockets of the northern Rockies and northern Minnesota, specifically Isle Royale. There are a few in scattered, remote areas of Mexico, not even enough to call them a breeding population.

Erect ears and a long muzzle are set in a heavy ruff of fur and are accented by distinct yellow eyes. Wolves have legs that look a bit too long and feet that are over-sized. The bushy tail is usually carried low, seldom raised above the level of the back. Males are slightly larger than females.

Wolves are quite variable in color. The Arctic tundra subspecies tends to be all white. Boreal forest wolves tend to be a mix, black to white. The more temperate climate wolves are many tones of brown and grey. The underbody is often lighter and the insulating fur of the winter coat is usually very light, causing the wolf to darken as that undercoat is shed. (source - www.chaffeezoo.org)
