The Cheetah, Acinonyx jubatus, is the fastest land animal, reaching speeds up to 70 miles per hour. A cheetah's footpads have grooves for better traction at high speeds, and its long tail provides balance in high-speed turns. Each cheetah can be identified by the unique pattern of rings on its tail.
