Superspeed on Land: Cheetahs

This quick cat is the world's fastest land animal, often sprinting at 65 miles (105 kilometers) an hour. Unlike big cats that stalk in packs, cheetahs generally overtake their prey by speed alone.

But cheetahs lack superstamina and can only run flat-out for distances of about 1,600 feet (500 meters). Sprinting farther would cause their bodies to overheata very real danger in the hot African savannas where cheetahs thrive.

Superspeed can have its drawbacks. According to recent reports, cheetahs are crashing more often as their grassland homes become bushiersometimes with tragic results. (See "Cheetahs Suffering More Fatal Crashes During Chases, Experts Say" [June 20, 2006].)
