How Strong Is a Wolverine? Strong Enough to Drag a Moose

A wolverine weighs maybe 40 pounds and can drag a moose across frozen ground. Not a whole moose—but a dead one, weighing several times what the wolverine does, moved by sheer muscle and leverage. That compact 40-pound body contains a bite force of 1,900 PSI. For comparison, a lion's bite is around 650 PSI. A wolverine's jaw can crack through bone so dense that other scavengers give up and wait for the wolverine to finish. They're built for theft. A wolverine will follow wolves or bears to a kill, wait for the predators to move on, then excavate the frozen carcass alone. Their legs are short and thick, positioned wide apart for stability and power. The claws—five inches long on the front paws—work like ice axes and can grip prey that's thrashing. Watch a wolverine climb a vertical tree trunk and you're watching an animal that could wrestle a bear twice its size, though it usually chooses not to. The reputation is real. Wolverines have been documented breaking into food caches built specifically to keep them out. A steel-reinforced cooler gets shredded. A snowmobile gets dismantled. In one documented case, a single wolverine destroyed a cabin's entire winter food supply and chewed its way through a metal door. No hesitation. No backing down. Size means almost nothing to a wolverine. What matters is density, leverage, and a willingness to commit to violence that most animals reserve for actual survival threats. A wolverine fights like every encounter is the end of the world. The moose thing might sound like exaggeration. It isn't.
