Wolverine: Super Strong

In 2007, biologist Audrey Magoun scanned the snowy Alaskan landscape from a small airplane. She was looking for a wolverine, an animal that she had been studying for the past 30 years. Suddenly, she saw a ball of brown fur below. Could it be the animal she'd been searching for?

Look inside to find out how Audrey and other Arctic researchers track and study wolverines-rough, tough animals that are always on the go. You'll also discover how wolverines are built to survive in some of the coldest places on Earth, how they hunt and protect themselves from enemies-and how humans can help save them and their icy habitat.
