Pronghorn Playground

The Pronghorn is a species of artiodactyl (even-toed, hoofed) mammal indigenous to interior western and central North America. Though not a true antelope (indigenous to regions in Africa and Eurasia), it is known colloquially in North America as the American antelope, pronghorn antelope, prairie antelope, or simply antelope. It is the only surviving member of the family Antilocapridae.

 

The Pronghorn is the fastest land mammal in the Western Hemisphere, being built for maximum predator evasion through running. The top speed is dependent upon the length of time over which it is measured. It can run 35 mph for 4 mi (56 km/h for 6 km), 42 mph for 1 mi (67 km/h for 1.6 km), and 55 mph for 0.5 mi (88.5 km/h for 0.8 km). While it is often cited as the second-fastest land animal, second only to the African cheetah, it can sustain high speeds longer than cheetahs. Compared to its body size, the pronghorn has a large windpipe, heart, and lungs to allow it to take in large amounts of air when running. Additionally, pronghorn hooves have two long, cushioned, pointed toes which help absorb shock when running at high speeds. The pronghorn has been observed to have at least 13 distinct gaits, including one reaching nearly 7.3 m (8.0 yd) per stride.
