The grey wolf

The Gray Wolf is the largest living member of the family Canidae. The largest individuals tend to be found in the northern forests of North America, with weights of 175 lb. having been recorded. A weight of 100-125 lb. is much more typical, however. Gray wolves from the hotter, drier parts of the world rarely exceed 50 lb.. In general, there is a wide size range among the various races, or "subspecies" of gray wolf. Their color also ranges vastly between the sub-species.
