Among the radiata, jellyfish and their kin, the main form of swimming is to flex their cup shaped bodies. All jellyfish are free-swimming, although many of these spend most of their time swimming passively. Passive swimming is akin to gliding; the organism floats, using currents where it can, and does not exert any energy into controlling its position or motion. Active swimming, in contrast, inv… WebMay 14, 2024 · So the propeller is both pushing and being pulled through the water. During this motion, the propeller produces axial and transverse thrust. The axial thrust produced by the propeller …
