Adaptations of the gray wolf relate to all aspects of its life, from hunting and digesting to fasting. Gray wolves are digitigrades, which means that only their toes touch the ground when they walk. This allows the gray wolf to be a highly skilled runner and hunter, reaching up to 35 miles per hour.
Once they've caught their prey, gray wolves use sharp canine teeth to penetrate and tear its flesh, and their rear molars and premolars are strong enough to crush bone. The gray wolf digests its meal slowly. It can eat around 20 pounds in one meal, then fast for two weeks while searching for its next kill.
