Shrimp - like critter the size of fleas could be the champion jumpers of the animal kingdom , scientists now let on .
After break down high - focal ratio video of three species of crustaceans known as copepods , researcher regain that within millisecond , each of these wee animal could apply its leaps to achieve speed of a thousand times its dead body length per s .
This shrimp-like critter, a copepod, could be the champion jumper of the animal kingdom, using leaps to achieve speeds of a thousand times its body length per second.
Since copepods are typically 1 to 2 millimeters long , that come to roughly 2 to 4 Swedish mile per hour ( 3 to 6.4 kilometer per time of day ) , which might not go like much . However , that would be the equivalent of a 5 ' 8 " soul reaching more than 3,800 miles per hour with a jump .
" The films we wanted lasted only one second , but they had to be the right one arcsecond , " said survey researcher Thomas Kiørboe , a nautical ecologist at the Technical University of Denmark . " fate and patience were the most important factor in pay off the veracious footage , and whenever we nonplus something exciting on the tv camera , everybody acclaim . "

These animals float by forceful strokes with their legs . The researchers ' calculations suggest that to overcome the drag of water viscousness ( resistance to motion ) the copepods’jumping musclesare some 10 time more forceful than any see in beast before .
" Relative to their size of it , copepods are stronger than describe for any other creature , " Kiørboe said . " And they are also faster , again comparative to their size , than any other aquatic animal . "
copepod crustacean apparently possess two different systems for propulsion — their eating appendages , which also find use in regular swimming , and four solidification of leg , which seem dedicated entirely to escape attempts .
" The outflow scheme is pitch for maximum short - terminus force out production , while the swimming system is geared for recollective - term execution , " Kiørboe said . Most other brute have just one propulsion system , which they ordinarily gear toward helping them survive over the foresightful - term if possible , he noted .
Copepods might be the most abundant multicellular fauna " not only in the sea , but on Earth , " Kiørboe total . This power of theirs to escapepredatorswith bursts of amphetamine could be " the samara to their evolutionary success , " he explained .
The scientist detail their findings online May 12 in the Journal of the Royal Society Interface .
