The wolverine is the largest land-dwelling member of the weasel family. It is a stocky, muscular animal covered in brown fur with lighter stripes along its sides. They are typically 25-35 inches long and weigh as much as 55 lbs.

Wolverines typically have litters of two to three kits in the spring. These kits reach adult size within one year. The lifespan of the wolverine is anywhere from 5 to 13 years. Wolverines are solitary animals, living on their own after they are full-grown.

A wolverine’s fur is long and dense. It is also very resistant to frost, because it does not retain water. This appealing fur has been used to line jackets, leading to the trapping and hunting of wolverine.

Wolverines actually do not have any natural predators. From time to time conflicts over food or territory can occur with other large predators like wolves or bear.

The wolverine’s range includes the arctic and alpine regions of Alaska, northern Canada, Siberia, and Scandinavia. It is difficult to estimate the world’s total wolverine population, because each wolverine keeps a separate territory. A male wolverine’s territory can be up to 240 square miles, while a female’s is between 50 and 100 square miles.
