North America and Eurasia.
Gray wolves can survive in many biomes as long as food is plentiful and the climate is relatively cold. The Siberian Taiga, one of the habitats they are best suited to, is a boreal forest with long, cold winters and short summers. In Canada and Alaska, the gray wolf population is stable. In most of North America, however, they are an endangered species. In Europe, Asia, and Africa, the remaining wolf populations are tiny. The largest wolf population in Europe and Asia is found in Russia, which includes the Siberian Taiga. The gray wolf or grey wolf (Canis lupus) also known as the timber wolf, or western wolf, is a canid native to the wilderness and remote areas of North America and Eurasia. It is the largest extant member of its family, with males averaging 43–45 kg (95–99 lb), and females 36–38.5 kg (79–85 lb).

A wolf is a canid, a carnivorous animal in the dog family. The wolf with its relatives the fox, coyote and domestic dog primarily eats meat. The adult wolf weighs 40 to 175 pounds. A typical wolf needs 3 or more pounds of food a day. It eats as much as 20 pounds at one feeding to last it through several days without food. A wolf eats large animals such as deer, elk and livestock. It also eats rabbits, mice, beavers, fish, berries and grass. A wolf depends on its sense of smell to find most food. The most common type of wolf is the gray wolf, or timber wolf. Adult grey wolves are 4 to 6.56 feet (120 to 200centimeters) long and weigh about 40 to 175 pounds (18 to 79 kilograms). Just like its name, the gray wolf typically has thick gray fur, although pure white or all black variations exist. Since they are carnivores, their meals consist of meat that they hunted. Gray wolves usually eat large prey such as moose, goats, sheep and deer. Normally, the pack of wolves will find the weakest or sickest animal in a herd, circle it, and kill it together. Size: Wolves vary in size depending on where they live. Wolves in the north are usually larger than those in the south. The average size of a wolf's body is 3-5 feet long. Their tails are usually 1-2 feet long. Females typically weigh 60-100 pounds, and males weigh 70-145 pounds. Today, gray wolves have populations in Alaska, northern Michigan, northern Wisconsin, western Montana, northern Idaho, northeast Oregon and the Yellowstone area of Wyoming. Mexican wolves, a subspecies of the gray wolf, were reintroduced to protected parkland in eastern Arizona and southwest New Mexico. Size is a key difference between coyotes and wolves. Coyotes range from 3.5 to 4.5 feet long, 16 to 20 inches high at the shoulder and 20 to 50 pounds. This is about half the size of a wolf. Coyotes tend to have gray or reddish brown fur with rusty colored legs, feet, and ears, and whitish fur on the throat and belly.  Wolves are the ancestors of all domestic dogs. There are two species of wolves in North America. The smaller species is the red wolf, Canis rufus, which has shorter, redder fur than the gray wolf. The gray wolf, Canis lupus, has thicker fur which is more gray or golden, and is larger than the red wolf.
