Wolves are descendants of a carnivore called Creodont which lived about 100 million years ago. The scientific name for the wolf is Canis lupis. Wolves may look very different from each other. Wolves in general have upright ears, sharp, pointed muzzles, inquiring eyes, and are very smart. Most adult males weigh about 75 to 125 pounds.
Males are generally bigger than females.
Wolves usually appear bigger than they really are because of their fur. On average wolves are about 50 to 70 inches long and 21 to 31 inches high at the shoulder. Wolves are a very social kind of animal. They run around in groups called a pack. The average wolf pack has about 7 or less wolves in it.
