PRONGHORN
Antilocapra americana
DESCRIPTION
Pronghorn (Antilocapra americana) is commonly known as the American antelope, although it is not a true antelope. This species is characterized by its unique horns, which are shed and regrown annually, and its remarkable speed, making it one of the fastest land mammals in North America. Pronghorns are social animals, often found in herds, and they inhabit open plains and grasslands, where they can easily spot predators.
FUN FACTS
- Pronghorns are the second fastest land mammals in the world, capable of reaching speeds up to 55 miles per hour
- Unlike true antelopes, Pronghorns are the only surviving members of their family, Antilocapridae, and have unique adaptations that allow them to outrun predators in their open habitats
