- Domain Eukarya: This domain has organisms who have a nucleus, and are either multicellular or single-celled.
- Kingdom Animalia: The members in this kingdom are not prokaryotes, and they don't have a cell wall. They are heterotrophs, and have organized tissues.
- Phylum Chordata: The organisms in this Phylum have bilateral symmetry, segmented body and muscles, three germ layers and a well developed coelom (a body cavity between the body wall and the intestine.). The organisms also have a complete digestive system with a nerve cord that most likely has a brain at the end.
- Subphylum Vertebrata: A organism that is in this Subphylum has a vertebral column, has two skin layers (an outer layer and an inner dense layer.), and the skin is usually changed so it produces hair, feathers, glands, etc.
- Class Mamalia: All mammals contain middle ear bones, hair (hair is present at some time in the mammal's life) , and the production of milk that is modified by sweet glands other wise known as mammary glands
- Order Carnivora: Most members of Carnivora usually have different styles of eating or general styles in particular, but they are mainly carnivorous. Members of the Carnivora class usually have special teeth that are a good method for cutting the meat and tendons of their prey. Also, most members also have a skull that varied in form.
- Family Canidae: Members of this family are primarily medium-sized flesh eaters, while being the more omnivorous than other carnivores. Many members have a special way of hunting their prey.
- Genus Canis: This genus has dogs, jackals, and wolves in it.
- Species: Canis lupis
- Height: The height for most wolves ranges from 60-90 cm. Height is measured from base paws to shoulders.
- Length: The length for most male wolves is 1000-1300 mm for gray wolves, while the weight for females is generally 870-1170 mm. Length for the tail is generally 350-520 mm.
- Weight: The general weight for a male gray wolf is 30-80 kg, but the average is weight is 55 kg. On the other hand, females generally weigh from 23-55 kg, while the average is 45 kg.
- Color: Color varies a lot with gray wolves. It mostly varies geographically. At birth all of the cubs have sooty brown fur. In arctic populations the fur can be pure white with gray, brown, cinnamon, and black. It can also sometimes be uniform black in different phases. The North American gray wolf has three color phases. In the normal phase it has some different types of white, containing shades of black, gray, and cinnamon. On the upper part of the animal the color is usually brown. The black phase includes the colors brown and black with white specks. The underparts are still usually pale. There is also a pure white spot in the middle of the gray wolf's chest. In the third phase the wolves drab-gray and overlaid with brownish-black. The underparts also become more pale.
- Natural Range: The gray wolf is frequently and commonly populated in lightly settled portions of Canada, Labrador, British Columbia, Yukon territory, and Northwest territories.
- Diet: The gray wolf's diet usually consist of large mammals such as deer, moose, caribou, elk, bison, and muskox. A small part of the gray wolf's diet is small mammals and birds.
- Habitat Description: Gray wolves are able to adapt to habitats very well. Some habitats it can adapt to are arctic tundras, forests, prairies, and landscapes. Some terrestrial biomes that the gray wolf can live in is the tundra, taiga, chaparral, forest, scrub forest, and mountains.
- Predators: The main predators for gray wolves is humans. Although other wolves from different packs will attack other wolves is they are either alone or young, or both.
