Gray Wolf (Canis Lupus Lupus)
The wolf, also known as the gray wolf, timber wolf, western wolf, and its other subspecies 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 43–45 kg (95–99 lb) and females 36–38.5 kg (79–85 lb). 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. Its winter fur is long and bushy and predominantly a mottled gray in color, although nearly pure white, red, and brown to black also occur. Mammal Species of the World, a standard reference work in zoology, recognises 38 subspecies of C. lupus..
