The grey wolf or grey wolf (Canis lupus) is native to the wilderness and remote areas of North America, Eurasia, and North Africa. It is the largest member of its family, with males averaging 43–45 kg (95–99 lb), and females 36–38.5 kg (79–85 lb). It is similar in general appearance and proportions to a German shepherd, or sled dog, but has a larger head, narrower chest, longer legs, straighter tail, and bigger paws. Its winter fur is long and bushy, and predominantly a mottled grey in colour, although nearly pure white, red, or brown to black also occur.
It is a social animal, travelling in nuclear families consisting of a mated pair, accompanied by the pair's adult offspring. The grey 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 mammals, though it also eats smaller animals, livestock, carrion, and garbage.
