An iconic northern species, an abundance of arctic foxes live within Wapusk National Park.

These omnivorous animals live in dens and are active year round. In the summer months, arctic foxes have a dark coat that is brown and black. As winter approaches, they begin to grow their white winter coat. The colour of the fur depends on the habitat they live in. Populations in rocky areas have more grey fur compared to those who live in areas with total snow cover, which results in a pure white coat. Their fur is one of the warmest of any mammal.

Arctic fox live in den complexes, often with multiple entrances and tunnels. They have large litters, which are reared by both parents.

Arctic fox eat whatever they can find on the tundra including small mammals, birds, eggs, berries and carrion. If food is abundant, these foxes will cache (bury) the surplus.
