The largest weasel species, the wolverine is a ferocious — and elusive — presence in the northern forests, mountains, plains, and tundra of North America, Europe, and Asia. These territorial carnivores will even take on bears, cougars, and wolf packs that try to move in on their kills. Watch as wildlife biologists check in with M3, one of the biggest, fiercest wolverines you’ll ever encounter.
Wolverine - [ No, he's not a pet. He's WAY too cranky to be domesticated, and you'd never be able to catch one anyway. You are extremely unlikely to ever even see one. (because he wants it that way!) If you doubt that he's a badass, I saw a video of a 50 lb. wolverine harassing a full grown grizzly bear. - PSC]
