Animal Facts
Although colloquially called an 'antelope', the pronghorn is actually more closely related to giraffes and okapis.
Pronghorn antelope are the second fastest land animal after the cheetah and can run at 61mph. However, they can run at high speeds for much longer than the cheetah.
Pronghorn antelope have a lot of adaptations for speed and agility, including a large heart and lungs, light bones and shock-absorbent hooves.
Pronghorn antelope have white glossy hairs on their rump which stand up and catch the light when the pronghorn is alarmed, acting as a warning to other herd members.
Although this species can jump up to 6m in one bound, they prefer to crawl underneath obstacles rather than jump over them.
