The Arctic Wolf, also called Polar Wolf or White Wolf, is a species of mammal of the family Canidae, and a subspecies of the Gray Wolf. Arctic Wolves inhabit the Canadian Arctic, Alaska and the northern parts of Greenland.
The Arctic Wolf inhabits the northern part of Greenland, the Canadian Arctic and parts of Alaska. They have lived in North America for more than two million years. When they find a den, they make a couple of chambers for food and young. Arctic wolves live on the islands of the Canadian Arctic, and the north coast of Greenland, roughly north of 70° North latitude. The Arctic Wolf is the only subspecies of the Gray Wolf that still can be found over the whole of its original range, largely because, in their natural habitat, they rarely encounter humans.
Like all wolves, Arctic Wolves hunt in packs, preying mainly on Caribou and Muskoxen, but also Arctic Hares, seals, ptarmigan and lemmings, and smaller animals such as waterfowl. To eat rodents they must pick up their scent and find the entrance to their tiny dens to flush them out. Wolves almost never attack humans. Due to the scarcity of prey, they roam large areas, up to 2,600 km2 , and follow migrating caribou south during the winter. They are not fast runners, instead relying on stamina to take down prey
