The wolf is the largest wild member of the dog family, distinguished from other Canis species by its less pointed ears and muzzle, a shorter torso and a longer tail. Adults measure 105 to 160cm in length and average about 40kg. The skull is 230 to 280mm long. It is related closely enough to the coyote and golden jackal to produce fertile hybrids (Wikipedia, general species account).
Of all Canis species, the wolf is the most specialised for cooperative hunting, shown in its physical adaptations for tackling large prey, its social nature, and its expressive behaviour including howling. Across its range it is an apex predator, feeding mostly on large hoofed mammals as well as smaller animals and carrion. Single wolves or pairs often hunt more successfully than large packs. Nationally Critically Endangered (Nepal National Red List 2011).
