ヤマトカワゴカイの遊泳挙動解析

抄録

We conducted the swimming behavior analysis of polychaete, Hediste diadroma (Nereididae) in the reproductive phase. Change of length and angle in parapodia and setae with movement time were analyzed. Flow field surrounding of polychaete while swimming was visualized using tracer of ion exchange resin particles, and velocity distribution were examined by Particle Image Velocimetry with the movement of parapodia. These results were discussed for the improvement of swimming speed for aquatic propulsion mechanism modeled on the polychaete worm's swimming.
