The pronghorn is a unique North American mammal known for its incredible speed and agility. It can run up to 55 miles per hour, making it one of the fastest land animals in the world. Pronghorns are easily recognized by their distinctive horns, which are made of a bony core covered in a sheath of keratin, similar to human nails. They inhabit open grasslands, deserts, and sagebrush areas, primarily in the western United States. Unlike true antelopes, pronghorns are the only surviving members of the family Antilocapridae. They have a unique adaptation that allows them to outrun predators, such as coyotes and mountain lions. Pronghorns are also known for their remarkable eyesight, which helps them detect danger from long distances. Their population has rebounded due to conservation efforts, and they are now a common sight in many protected areas.
