Wolverine

The wolverine is the largest land-dwelling member of the weasel family, found in the boreal forests and tundra of the far Northern Hemisphere across North America, Europe and Asia, recognized by its stocky, muscular build, thick oily fur and powerful jaws and claws adapted for a demanding, wide-ranging life in harsh, cold environments. It has a reputation, well supported by its behavior, for tenacity and strength disproportionate to its size, capable of driving larger predators such as wolves and bears away from carcasses and of taking down prey much larger than itself when the opportunity arises, though it survives mainly by scavenging. Wolverines are solitary and range over enormous territories in search of scattered food, needing large stretches of undisturbed wilderness, and the species is classified as vulnerable due to habitat fragmentation and sensitivity to climate change affecting the snow cover it depends on for denning.
