Nannosquilla decemspinosa is a species of long-bodied, short-legged mantis shrimp. It lives in shallow sandy areas along the Pacific coast of Central and South America.

It is most well known because when stranded by a low tide the 3 cm stomatopod lies on its back and performs backwards somersaults over and over. The animal moves up to 2 meters at a time by rolling 20-40 times, with speeds of around 72 revolutions per minute - 1.5 body lengths per second (3.5 cm/s). Researchers estimate that the stomatopod acts as a true wheel around 40% of the time during this series of rolls. The remaining 60% of the time it has to "jumpstart" a roll by using its body to thrust itself upwards and forwards.{{cite web|url = http://www.abc.net.au/science/k2/moments/s42510.htm |title = Great Moments in Science - Real Wheel Animals - Part Two |accessdate = 2008-08-03}}{{cite web|url = http://www.nwf.org/nationalwildlife/article.cfm?issueID=77&articleID=1114 |title = Who You Callin' "Shrimp"? |author = Pamela S.
