- The wolverine is a powerful animal that resembles a small bear but is actually the largest member of the weasel family.
- These tough, solitary animals may travel 15 miles in a day in search of food such as porcupines, hares, marmots, and ground squirrels. With an advantage in deep snow, they can also take down much larger animals, including caribou and moose. During the summer season, they will also occasionally eat small plants and berries.
- They have strong jaws and teeth, and can crush right through bones and teeth of their prey. They even have a specialized tooth that allows them to eat frozen carcassses.
- Their thick fur once made them a prime target for trappers in North America. The fur was used to line the hoods of parkas, though this is far less common today. They are protected in many areas.
