Antilocapridae is a family of mammals that includes the pronghorn, a unique species found primarily in North America. These animals are known for their incredible speed and endurance, making them one of the fastest land mammals. Pronghorns have distinctive horns that are shed and regrown annually, which is a characteristic feature of this family. The Antilocapridae family is often considered a living fossil, as it has existed for millions of years. Unlike true antelopes, pronghorns are the only surviving members of this family, showcasing a unique evolutionary path. They inhabit open grasslands and are well-adapted to their environment, relying on keen eyesight and agility to evade predators.
