Often called the "polar wolf" or "white wolf," Arctic wolves inhabit the Arctic regions of North America and Greenland. Thanks to its isolation, the Arctic wolf is not threatened by hunting and habitat destruction in the same way as its southern relatives. Arctic wolves are smaller than gray wolves, They also have smaller ears and shorter muzzles to retain body heat. In the wild, Arctic wolves primarily prey on muskoxen and Arctic hares. They have also been found to prey on lemmings, caribou, Arctic foxes, birds, and beetles.
Length: about 1-1.8 m, including tail.
Weight: 45-70 kg
Arctic Wolves usually have small ears, which help the wolf maintain body heat. The alpha male is always the largest and will continue growing after other wolves had stopped. Arctic wolves can be black, gray or white.
The lifespan of the Arctic wolf is from 7 to 10 years in the wild and up to 20 years in the captivity.
Arctic wolves have two thick layers of fur. The outer layer actually gets thicker as the winter months come along. The first layer helps to form a waterproof barrier for the skin. As a result, their body temperature can stay warm enough even when it is bitter cold.
Arctic wolves have almost completely white fur all year, which allows them to blend into their snowy surroundings.
