A wolf is a dog-like mammal belonging to the Canidae Family. The Gray Wolf, also known as the Timber Wolf, is the most popular species of Wolf. The Gray Wolf lives in either wooded areas, or open spaces, and can quickly adapt to either one if necessary. Due to hunting, it is almost, if not completely eliminated from Europe, but still lives in some parts of Asia, and North America, from Alaska to the Northern states. The Gray Wolf is a powerful animal, with strong legs, limber joints, a deep but narrow chest, large feet, and a narrow head. Other than some domestic breeds of dogs, the Gray Wolf is the largest animal in the Canidae Family. A full grown adult male Gray can be up to 6.6 feet long, including it's tail, and weigh up to 100 to 110 pounds. The female Gray is usually smaller than the male. The fur of a Gray Wolf is (obviously) usually gray, but can be brown, white, black, or reddish. The Gray Wolf is an intelligent, social mammal. The American Indians admired the Gray Wolf, because of it's beauty, speed, strength, and skill.
