The wolf (Canis lupus; [b] pl.: wolves), also known as the gray wolf or grey wolf, is a canine native to Eurasia and North America. More than thirty subspecies of Canis lupus have been recognized, including the dog and dingo , though gray wolves, as popularly understood, only comprise naturally-occurring wild subspecies.
Canis is a genus of the Caninae which includes multiple extant species, such as wolves, dogs, coyotes, and golden jackals. Species of this genus are distinguished by their moderate to large size, their massive, well-developed skulls and dentition, long legs, and comparatively short ears and tails. [ 3 ]

The dire wolf (Aenocyon dirus[10] / iːˈnɒsaɪ.ɒn ˈdaɪrəs /) is an extinct canine. The dire wolf lived in the Americas (with a possible single record also known from East Asia) during the Late Pleistocene and Early Holocene epochs (125,000–9,500 years ago). The species was named in 1858, four years after the first specimen had been found.
The red wolf's taxonomic classification as being a separate species has been contentious for nearly a century, being classified either as a subspecies of the gray wolf Canis lupus rufus, [9] [10] or a coywolf (a genetic admixture of wolf and coyote). Because of this, it is sometimes excluded from endangered species lists, despite its critically ...
