Fig. 6. Simulated anuran swimming during maximal foot translation and rotation. The
top panel shows swimming velocity traces (dashed black line), total thrust
(green line), and translational (red line) and rotational components of thrust
(blue line). The bottom panel shows 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.
