Gulo

Gulo is a genus of mustelid containing a single living species, the wolverine (Gulo gulo), the largest terrestrial member of the weasel family. Wolverines are stocky, low-slung animals resembling an oversized fisher, with males weighing 11 to 18 kilograms and females 8 to 12 kilograms, and body lengths of 65 to 109 centimeters; their thick, dark, oily fur is hydrophobic and frost resistant, and their upper molars are rotated ninety degrees, allowing them to gnaw frozen carrion. They inhabit the remote boreal forests and subarctic and alpine tundra of the Northern Hemisphere, concentrated in northern Canada, Alaska, the Nordic countries, and western Russia and Siberia, though trapping, habitat loss, and fragmentation have contracted their range since the nineteenth century. Solitary scavengers that often follow wolf and lynx trails to feed on kills, wolverines are also capable of actively hunting prey much larger than themselves.
