The Australian tiger beetle Cicindela eburneola, is one of the fastest running insects in the world relative to body size, which has been recorded at 6.8 km/h (4.2 mph) or 171 body lengths per second.
The cheetah is famously the fastest land animal on the planet, running at up to 120 kilometres an hour (75 miles per hour).
The peregrine falcon is the fastest aerial animal, fastest animal in flight, fastest bird, and the overall fastest member of the animal kingdom. Though it is not fast enough in horizontal level flight, its hunting dive, the stoop, it soars to a great height, then dives steeply at speeds of over 200 mph.
