Wolverine

Gulo gulo

A tough, stocky member of the weasel family from the far north that can drive bears and wolves away from food.

About the Wolverine

Wolverines live in cold northern forests, taiga, mountains and tundra in northern Europe, Asia, Canada and Alaska. They are 25 to 34 inches long and weigh 24 to 40 pounds. Thick, oily fur sheds water and frost, and wide paws help them move through deep snow. They eat mostly meat, including squirrels, rabbits and birds, plus berries and eggs in summer, and they often eat carrion.[1]
