Pronghorns are true American natives, found nowhere else in the world.
In Wyoming, home to the world's largest herd of pronghorn, the animals outnumber the people. The outer sheath of the horn falls off each fall and grows back by the following summer. The fastest North American mammal, pronghorns can reach speeds of 60 miles per hour and are known to run for long distances at speeds of 30 to 40 miles per hour.
