Swimming efficiencies of fish and cetaceans have been related to a certain synchrony between stroke cycle frequency, peak-to-peak tail/fluke amplitude and mean swimming speed. These kinematic parameters form a nondimensional wake parameter, referred to as a Strouhal number, which for the range betwe...
