Pronghorns at full speed.
The Pronghorn is the only living member of its family.
It is the fastest land mammal in the world. It can sprint as fast as 60 mph and can sustain a speed of 30 mph for miles! The African Cheetah is often credited with being the fastest, but it is only a sprinter who flags out after a few hundred yards. No other land mammal can keep up with the Pronghorn over a long distance.
When they encounter a fence a Pronghorn will usually crawl under it! They seldom jump over one.
