The gray wolf (Canis lupus) goes by a many names such as the timber wolf or western wolf. Wolves are typically pretty social, intelligent, and kind creatures that live in groups called packs. The amount of wolves in a pack can vary greatly, but they usually consist of 5-8 members. These wolves tend to develop strong social bonds within their packs. Packs are led by the alpha male and/or female. The alpha pairs are usually the biological parents of the pack, since it usually consists of their offspring. Speaking of offspring, wolf pups are born blind, deaf, and essentially defenseless. They are cared for by the pack until they are about 10 months old since that’s usually when they can hunt on their own. Once these wolves are a year old, some may leave the pack to simply join others, or to breed. These wolves have been known to travel from 50 to 500 miles (80-805km). Wolves are also considered to be keystone predators, since they help maintain a balanced ecosystem, and are apex predators.

Gray wolves vary in size depending on where they live in. However, males are usually larger than the females. For example, male wolves usually range from being 5ft to 6.5ft long (1.5m-1.98m), and generally weigh from 75 to 145 lb (34-65.8kg). Meanwhile, the females typically range from 4.5ft to 6ft (1.4m-1.8m), and weigh from about 60-100 lb (27.2-45.4kg). Also, most wolves have a height between 2-3ft (61-92cm).

Their fur coloring also varies depending on where they reside. Their fur colors can range from being white with gray to brown to tawny, and to some being nearly all uniform black or white. The gray fur coloring does tend to dominate though, hence the name, the Gray wolf. Thick fur is also present among these wolves. The outer layer of fur is composed of coarse guard hairs while below it, a soft undercoat is present. Wolf fur tends to grow thicker during autumn and winter. This fur sheds during the late spring, and this results in the wolf having a short summer coat.

Gray wolves can survive in a wide variety of habitats where suitable food is available, although it’s generally absent from heavily populated human settlements and areas of intensive cultivation. They can be found in forests, tundras, taigas, plains, mountains, and even deserts.

Although gray wolf populations are stable worldwide, they are considered to be very vulnerable on a regional level. This is due to habitat loss, trapping, shooting, poisoning, and more.
