Wolf, any of two species of wild doglike carnivores. The gray, or timber, wolf (Canis lupus) is the better known. It is the largest nondomestic member of the dog family (Canidae) and inhabits vast areas of the Northern Hemisphere. The Ethiopian, or Abyssinian, wolf (C. simensis) inhabits the highlands of Ethiopia; until recently it was considered a jackal.Keen senses, large canine teeth, powerful jaws, and the ability to pursue prey at 60 km (37 miles) per hour equip the wolf well for a predatory way of life.
The wolf is built for travel. Its long legs, large feet, and deep but narrow chest suit it well for life on the moveA typical northern male may be about 2 metres (6.6 feet) long, including the bushy half-metre-long tail. Standing 76 cm (30 inches) tall at the shoulder, it weighs about 45 kg (100 pounds), but weight ranges from 14 to 65 kg (31 to 143 pounds), depending on the geographic area. Females average about 20 percent smaller than males. The largest wolves are found in west-central Canada, Alaska, and across northern Asia.
