The timber wolf (Canis lupus) also known as the gray wolf, true wolf or western wolf is a canid native to the wilderness and remote areas of North America, Eurasia, and North Africa. Its the largest extant member of its family with males averaging 95-99 lb and females 79-85. 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, or brown to black also occur. The timber wolf is the most specialised member of the genus Canis, as demonstrated by its morphological adaptions to hunting large prey, its more gregarious nature, and its highly advanced expressive behavior. itb is nonethless closely related enough to smaller Canis species, such as the eastern wolf, coyote and golden jackal to produce fertile hybrids. It is the only species of Canis to have a range encompassing both the Old and New Worlds, and originated in Eurasia during the Pleistocene, colonizing North America on at least three separate occasions during the Rancholabrean. It is a social animal, travelling in nuclear families consisting of a mated pair, accompained by the pair´s adult offspring. The timber wolf is typically an apex predator throughout its range, with only humans and tigers posing a serious threat to it. It feeds primarily on large unglates, though it also eats smaller animals, livestock, carrion, and garbage. The timber wolf was once one of the world´s most widely distributed mammals, living throughout the northern hemisphere north in North America and in India. Howerver deliberate human persecution has reduced the species range to about one third, due to livestock predation and fear over attacks on humans. The species is now extinct in much of Western Europe, in Mexico and much of the USA.
