Gray Wolf (Canis lupus)
This large dog-like animal is usually gray but can vary from silvery-white to black. At maturity its length is approximately 40-52 inches. Although maligned through the ages as a vicious predator, the wolf might better be admired for its complex social organization. The leader, or alpha male, appears to control the pack's activities.

The Grey Wolf is considered the largest member of the wild dog family. Mainly found in the Northern Hemisphere, their numbers have declined over the years. Preferring to hunt in packs during the night, they feed on deer, elk, and other animals.

Wolves are social predators that live in nuclear families consisting of a mated pair, their offspring and, occasionally, adopted immature wolves.
Genetic studies reaffirm that the gray wolf is the ancestor of the domestic dog.
