Fig. 5. Simulated anuran swimming. Power strokes are shown for three different conditions: (A) maximum foot rotation with no translation, (B) 50% maximum translation and rotation, (C) maximum translation with no rotation. For all conditions, top panels show swimming velocity traces (dashed black line), total thrust (green line), and translational (red line) and rotational components of thrust (blue line). Bottom panels show total thrust (green line), and added mass-based (red line) and drag-based (blue line) thrust. Translational and rotational velocities are in phase for all conditions shown. Note that total thrust traces are identical for top and bottom panels.
