Gray Wolf

The Gray Wolf (Canis lupus; other forms: Timber Wolf, Wolf;

British English: Grey Wolf) is a mammal of the Canidae family.

The wolf shares a common ancestry with the domestic dog, and, according to most experts, is likely the progenitor of all dogs as they exist today.

Gray wolves, being keystone predators, are integral components of the ecosystems to which they typically belong.
