The Arctic wolf is smaller than its European cousin but it is heavier. They are part of the same species, canis lupus. Its way of life is basically the same as that of other wolves.
It lives in the glacial cold of the North, so it must survive temperatures as low as -60°C. For this reason it has a small round nose, a thick coat and wide paws for moving in snow.
In the wilds of northern Canada, the wolf is known as the doctor of the caribou since by preying on the weakest, it leaves the herds in good health.
