macropalpis is far in excess of the previous record holder, the Australian tiger beetle Cicindela eburneola, which is the fastest insect in the world relative to body size, with a recorded speed of 1.86 metres per second (6.7 km/h 4.2 mph), or 171 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), or approximately Mach 1.7. On this basis the 'fastest' organism on earth, relative to its body length, is the Southern Californian mite, Paratarsotomus macropalpis, which has a speed of 322 body lengths per second. When drawing comparisons between different classes of animals, an alternative unit is sometimes used for organisms: body length per second. Among the fastest animals in the sea is the black marlin, with uncertain and conflicting reports of recorded speeds. The peregrine falcon is the fastest bird, and the fastest member of the animal kingdom, with a diving speed of over 300 km/h (190 mph). This is a list of the fastest animals in the world, by types of animal. You can help by adding missing items with reliable sources. This is a dynamic list and may never be able to satisfy particular standards for completeness.
