Pronghorn

The fastest land mammal in the Western Hemisphere can run at speeds of up to 89 km/h (55 mph)

Thomas Wolf

Pronghorns are truly an animal of the past since they evolved to be fast enough to run away from prehistoric predators like the now-extinct American cheetah. While you might confuse them for a deer or an antelope, they actually belong to a different family with only one species, them!

In most deer and antelope species, only the males have antlers, while similar to pronghorns, they are the only animal with branched horns and not antlers. They shed their horns each year; the outer sheath falls away in the autumn and grows back in the summer. Pronghorns graze on grasses, forbs, and cacti in the summer. In the winter, they eat sagebrush and other plants.
