WOLVES: These carnivores and nocturnal mammals related to the dog family. Gray wolves are the most common measuring 4 to 6 feet in length and can weigh up to 170 pounds. Wolves are social creatures living and hunting in packs of 6 to 10 animals. The pack leader, called an alpha male, and his female mate are the only two wolves that produce any wolf pups. Wolves are known for their distinctive howls in which they communicate with the pack or leave territorial messages.
