The gray wolf or grey wolf, also known as the timber wolf

The gray wolf or grey wolf (Canis lupus[a]), also known as the timber wolf or western wolf,[b] is a canine native to the wilderness and remote areas of Eurasia and North America. It is the largest extant member of its family, with males averaging 4345 kg (9599 lb), and females 3638.5 kg (7985 lb).[6] Like the red wolf, it is distinguished from other Canis species by its larger size and less pointed features, particularly on the ears and muzzle.[7] Its winter fur is long and bushy, and predominantly a mottled gray in color, although nearly pure white, red, or brown to black also occur.
