In this paper we discuss the dynamics and efficiency of the two-joint bending mechanism composed of a streamlined body and a rectangular caudal fin. As the next topic to the analysis method and the performance of a typical body form in the previous papers, in this paper, we investigate the effect of variation of the body form parameter on the characteristics of the propulsive efficiency, and compare the results with dolphin observation data. It is found that two joints should be located at posterior position of the body to obtain high propulsive efficiency. It is also found that the reduced frequency of the motion for the dolphin observation data is somewhat larger than the optimum reduced frequency for maximum propulsive efficiency in the present analysis.
