Wolverines are one of the larger species in the weasel family. A stocky, muscular animal, the wolverine averages about 13 kg (30 lb.) in weight. The wolverine has been credited with the ability to defend its food against wolves and even grizzly bears.

Like other weasels, wolverines are pugnacious, bold and curious. It is primarily solitary, is active both day and night, and seldom seeks shelter even in the most severe winter weather.

The wolverine is omnivorous and consumes a wide range of edible roots and berries, carrion, small game and fish. They have been known to kill animals as large as caribou and mountain goats. They often follow migrating herds of caribou and clean up carcasses left by wolves and bears, crushing the bones with their powerful jaws.

The wolverine's range is extensive: individual animals often have a movement pattern that exceeds 30 km (18 mi.) per day. In North America, the animal is found primarily in the northern regions of Canada, between the tree line and the Arctic coast. Wolverines also occur in Europe and northern Asia.
