They inhabit the western parts of North America from Canada to northern Mexico. Males grow horns 12-18 inches in length. The sheaths of these horns are shed each year after the breeding season.
Females can grow short horns three to four inches in length.
A pronghorn's coat provides insulation during the winter. It is then molted in the summer. Pronghorn can erect their hair to allow for the release of body heat. They also have keen eyesight and sharp hooves that can be used for protection from predators. A pronghorn will raise its white rump and give off alarm odors to signal danger to the rest of the herd.
