Wolves have a number of physical qualities that can help them in their activities and environment. First, they have two layers of fur. Some wolves live in the frigid temperatures of the Arctic. These two layers help them stay warm when it is well below zero. Wolves' large paws help them get a good grip on snowy or icy surfaces. This helps them hunt. Lastly, their long legs help them run very fast. They can sprint up to 40 miles per hour. This ability to run at very high speeds is also very helpful during a hunt.
