Pronghorn antelope

Average speed: 61 mph

The pronghorn antelope is a type of hoofed mammal found in the grasslands of western North America. It can run at 61mph and maintain this speed for two hours. The antelope uses its speed as its main protective weapon against predators by outrunning and outlasting them. It can sustain its top speed much longer than a cheetah due to its larger heart and lungs. Compared to others of the same family, the pronghorn cannot jump effectively, so it compensates by running very fast.
