The purpose of this research is to clarify swimming mechanism of Water flea which could be a model of micro-machine. Its motion and flow around it have been experimentally visualized by microscopic particle image velocimetry (PIV). Water flea swims pushing water behind generating two type vortices. One is around its body and another is at the tip of second antenna. Study on the effects of these vortices are underway and it seems vortex around its body plays a role for propulsion.
