The fastest land animal is the cheetah, which has a recorded speed of 109.4-120.7 km/h (68.0-75.0 mph). The peregrine falcon is the fastest bird and the fastest member of the animal kingdom with a diving speed of 389 km/h (242 mph). The fastest animal in the sea is the black marlin, which has a recorded speed of 129 km/h (80 mph). (New studies show the top speed is only 58 mph, and that the accepted top speed of 70 + mph were in error)
While comparing between various classes of animals, a different unit is used, body length per second for organisms. The fastest organism on earth, relative to body length, is the South Californian mite Paratarsotomus macropalpis, which has a speed of 322 body lengths per second. The equivalent speed for a human running as fast as this mite would be 1,300 mph (2,092 km/h). This is far in excess of the previous record holder, the Australian tiger beetle, Cicindela eburneola, the fastest insect in the world relative to body size, which has been recorded at 1.86 metres per second (6.7 km/h; 4.2 mph) or 171 body lengths per second. The cheetah, the fastest land mammal, scores at only 16 body lengths per second while Anna's hummingbird has the highest known length-specific velocity attained by any vertebrate.
