Fig. 2. Outlines of swimming manatee. (A) The position of points (red circles) on body used for kinematic analysis. The horizontal line represents the body length of the manatee and vertical lines represent the peak-to-peak amplitude of each point. (B) Sequential outlines of the lateral view of a swimming manatee during one complete stroke cycle. Maximum vertical displacement is confined to the tip of the caudal flukes moving along a sinusoidal pathway.
