Despite weighing just 20 to 50 pounds, wolverines have been known to go after deer and even caribou if they’re hungry enough. Mostly, they don’t have to, but their voracious appetite means they can devour a smorgasbord of smaller critters (rabbits, squirrels, voles, beavers, etc) in a short period, using sharp, dagger-like claws and a powerful bite with a mouth that includes special molars for crushing bone.
