2. Pronghorn Antelope
The pronghorn antelope is now the fastest land animal in the northern part of the world after the American cheetah became extinct. Anatomically speaking, the pronghorn antelopes have large lungs and heart to support its stunning speed of 63 mph. The eye sight of pronghorn antelope is extraordinary because it can see as clear as a high powered binocular. Because of its weight of about 90 to 120 pounds, it prefers crossing underneath objects rather than jumping over them.
