The Gray Wolf's range currently covers most of Canada and Alaska. Historically, wolves occupied grasslands, forests,deserts and tundra. Presently they are mostly restricted to forests, stream side woodlands and Arctic tundra. Most Wolves resemble a long-legged German Shepard dog, with extra large paws and bushy tail. Although typically a gray color, the Wolf's coat can range from coal black to creamy white. A black Wolf is most common in dense forests and a whitish Wolf is a characteristic of the Arctic. Weight varies from 57 to 170lbs.(26-77kg ). A Wolf pack can occupy 100-300 square miles(260-780km). Hunting together in packs, members can catch much larger prey than when hunting alone. Ungulates comprise of 80% of the Wolf's diet. The gray Wolf is often referred to as the Timber Wolf.
