Known as the pronghorn, Antilocapra americana is a swift ungulate found in North American grasslands. It features distinct forked horns, a reddish-brown coat, and a white rump. Remarkable for its speed, it can run up to 55 mph, making it the fastest land mammal in the Western Hemisphere.

Antilocapra americana, commonly known as the pronghorn, is native to North America. Its geographical distribution covers the central and western parts of the United States, extending into southern Canada and northern Mexico. Key regions include the Great Plains, the deserts of the southwest, and semi-arid areas of the western United States.

Pronghorns typically inhabit open plains, grasslands, and deserts. They prefer areas that provide wide visibility and sparse vegetation, which aids in predator detection. The climate in these habitats ranges from arid to semi-arid, with seasonal temperature variations. Pronghorns are well adapted to environments with limited water resources.

The pronghorn occupies a niche as a primary consumer in its ecosystem, feeding predominantly on a variety of shrubs, forbs, and grasses. It has adapted to the open terrain by developing exceptional speed and endurance, which are crucial for evading predators. The pronghorn's ability to digest tough vegetation allows it to thrive in areas where other herbivores might struggle.
