The Arctic wolf (Canis lupus arctos) is also known as the polar wolf. They are a subspecies of the Grey wolf.  Arctic wolves are found primarily in the northern parts of Canada and Greenland.

Arctic wolves are smaller than other grey wolves. They weigh between 32 and 70 kg (70 and 154 lbs) and measure between 1 and 1.8 metres (3.2 and 8 feet). Arctic wolves are adapted to the harsh conditions of the Arctic tundra. They have large paws covered with fur that help them walk on snow without falling through it. They have shorter, rounded ears to be less exposed to cold winds. The Arctic wolves' thick fur keeps them warm in the winter when the temperatures drop to -30°C (-22°F). Their white coat also helps them camouflage themselves in the snow.

Finding food in the Arctic can be challenging. Arctic wolves can go several days without eating and can travel up to hundreds of kilometres in search of prey. Arctic wolves maintain the balance of the ecosystem they live in by controlling the population of other animals in the region, such as musk ox, Arctic hares and caribou.

Arctic wolves live in packs ranging between 5 and 10 individuals and often communicate with each other by howling. Their packs have a distinct hierarchical structure. Every pack has an alpha pair, a male and a female, who lead the pack. Living in packs helps Arctic wolves hunt and care for their offspring. Newborn pups are blind and deaf; their survival depends entirely on their mother and the pack.
