| Outline of Final Research Achievements |
Among aquatic organisms, dolphins have highly locomotive power and can do tail stands, lifting their bodies above the water. However, the dynamics of the tail stand have not been analyzed in detail, and how the dolphin achieves the tail stand has not been fully clarified. In this study, we took the video of the motion behavior of the Pacific white-sided dolphins over and in the water during the tail stand and analyzed their three-dimensional motions. We examined how the dolphins generate the thrust to lift their body over the water. The results were transferred to an underwater propulsion mechanism using fins based on the dolphin's tail fin to achieve higher thrust.
