Their general coloration is a grizzled gray but there are many other color variations including white and black. A large male gray wolf may be as tall as 3 feet at the shoulder and weigh more than 100 pounds. Female gray wolves tend to be smaller than the males. Gray wolves are powerful animals designed for chasing large prey. Their jaws are very strong with teeth similar to other large meat-eating animals like the lion and tiger.
Wolves also possess excellent senses of sight and hearing.
Within the pack, there are very defined rankings of individual animals. The pack is led by a dominant male and female who do most of the breeding. Members of the pack communicate between each other by using a variety of sounds including howls, whines, yelps, and growls and also by the use of various facial expressions and body postures. Wolves feed on a variety of different prey, both large and small, including rodents, rabbits, and deer. In taking larger prey, the wolf pack works as a team to coordinate its efforts to make the kill.
