Wolves (Canis lupus)  also known as gray wolves or grey wolf, are large canines native to Eurasia and North America. They are the  largest extant member of Canidae, with males averaging 40 kg  and females 37 kg . On average, wolves measure 105–160 cm (41–63 in) in length and 80–85 cm (31–33 in) at shoulder height.

Wolves are also distinguished from other Canis species by their less pointed features, particularly the ears and muzzle. Wolves are nonetheless closely related enough to smaller Canis species, such as the coyote and the golden jackal, to produce fertile hybrids with them. 

The winter fur of wolves is long and bushy and predominantly mottled gray, although nearly pure white, red and brown to black colours also occur. Up to 38 subspecies of wolves have been recognised including the domestic dog.
