notes
Pronghorn Antelope
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. The pronghorn may have evolved its running ability to escape from now-extinct predators such as the American cheetah. (Wikipedia)
