Wolf

Wolf.
The wolf (Canis lupus) is a large canine native to Eurasia and North America. It is the largest extant member of Canidae, males averaging 40 kg (88 lb) and females 37 kg (82 lb). On average, wolves measure 105–160 cm (41–63 in) in length and 80–85 cm (31–33 in) at shoulder height. Compared to coyotes and jackals, wolves have more pointed ears and muzzles, as well as shorter torsos and longer tails. The fur of a wolf is usually mottled white, brown, gray, and black. Up to 38 subspecies have been recognized, including the domestic dog. Wolves live in nuclear families consisting of a mated pair accompanied by their offspring. Fights over territory are among the principal causes of mortality. The wolf is mainly a carnivore and feeds primarily on large wild hooved mammals, though it also eats smaller animals, livestock, carrion, and garbage. Most recorded wolf attacks on people have been attributed to rabies. They have been both respected and feared in human societies.
