Who on light of all quicker?

to find out who on our planet the fastest, biologists “balanced in the rights“ big and little animals, having used peculiar unit of speed - the body length second. In new measuring system the tick from South California who much exceeded indicators of the absolute champion of speed - a cheetah was the champion. The second place in a rating of the fastest is held by a bug the Australian tiger.

To find out who on our planet the fastest, biologists “balanced in the rights“ big and little animals, having used peculiar unit of speed - the body length second. Surprisingly, but the speed of movement of a tick measured thus from South California much more exceeded indicators of the absolute champion - a cheetah.

The tick of Paratarsotomus macropalpis showed the result by 20 times exceeding achievements of a cheetah. If the insect was of the size of the person, then his speed would exceed 2 thousand kilometers per hour. The tick can run with a speed of 322 lengths of a body a second that is done by an insect whose size does not exceed a sesame sunflower seed, the fastest land inhabitant of our planet.

According to new research a bug the Australian tiger (Cicindela eburneola) which was considered earlier by the champion holds the second place in a rating now and follows Paratarsotomus macropalpis. The tiger can rush with a speed of 171 the body length second.

As for a world famous cheetah, it only on the fifth position with pathetic result of 16 lengths of a body in a second. On hunting cheetahs disperse to 110 - 115 km/h that for overland animals - an absolute record. At the same time the relative champion a tick moves with a speed of the hurrying pedestrian - 6,4 km/h.

To measure results of a tick, the student from the Californian College Pittsera (Pitzer College) and the chief author of research Semuel Rubin (Samuel Rubin) chased insects the whole summer. As a result he not only set a new world record, but also learned about physiology of the movement of animals much.

“It is healthy, to find something faster, than all the rest, - Rubin told. - But, in addition, looking more deeply, the physics of how they reach such speed can inspire new revolutionary projects for such things as robots or biomimetic devices“.

Rubin`s curator, professor of biology and the doctor of philosophy Johnathan Wright (Jonathan Wright), paid attention during occupations, how fast pincers touch pads. But to Rubin nobody fixed the speed of the movement Paratarsotomus macropalpis in a native habitat.

With reduction of the sizes of animals both their relative speed, and frequency of steps increases. Theoretically, the certain limit point limiting the frequency of movements of legs has to be found. “We considered the general question of whether there is the top limit of relative speed or frequency of steps which can be reached, - Wright told. - Comparison of indicators of pincers and other animals, shows that if the top limit is, then we did not find it yet“.

A tick of Paratarsotomus macropalpis - an endemic of South California. Though it was for the first time described in 1916, still little it is known of its habits and sources of food. For record of movements of a tick in vitro and in habitat the research group used high-speed chambers. “It was, actually, quite difficult, to catch them and when we removed on the street, it was necessary to follow them as a camera view only about 10 centimeters in the diameter“, - Rubin reported incredibly quickly.

The Californian pincers surprised researchers not only speed. It turned out that they easily transfer temperature of 60 degrees, running on the concrete heated by the sun. “They are active at temperatures which, apparently, stop activity of any other group of animals“, - Wright claims.
