This is one weasel you don't want to mess with. Its aggressive nature is widely known, thanks to the popularity of the X-Men comics and movies. Armed with powerful jaws, sharp claws and a thick hide, the wolverine can take down prey as large as a moose and steal food from bears and wolves.
Wolverines are perhaps best known for their attitude, says PBS. "They don’t hesitate to fight with wolves and other predators over a meal, and given the right snow conditions are even capable of taking down a moose—a feat wolverine specialist Doug Chadwick likens to 'a house cat bringing down a deer.'”
