Mammals that lived on the land masses of Northern Canada, able to survive in the polar deserts are the polar bear (Ursus maritimus), and the Arctic fox (Vulpes lagopus). Recent statistics show there are 26,000 polar bears worldwide, of which two of the three largest sub-populations are found in the Canadian Arctic.
