Have you seen a Wolverine?

The wolverine (Gulo gulo) is the largest member of the weasel (mustelid) family. With short, rounded ears, a broad head and a stocky body, wolverines are sometimes mistaken for small bears. Their tails, however, are bushy and relatively long. Their feet are large and during the winter have stiff hairs that aid in insulation and walking on top of the snow. Wolverines have unique coloration and markings: they are medium to dark brown with broad yellowish brown stripes down their sides and across the forehead. Males are larger than females, and full-grown adults in the lower 48 states typically weigh about 25-35 pounds (less than a blue heeler); adults are 3 to 3 ½ feet long. To learn more about wolverines, please see the Wolverine Identification Guide.
