Fig. 2. Kinematic and hydrodynamic function of dorsal and anal fins during steady
swimming at 0.5 L s-1. Red and blue represent dorsal and
anal fins, respectively. Solid lines represent fin kinematic oscillations over
time. Red and blue arrows represent the direction and magnitude of fluid jets
produced by fins. Green boxes on the fish indicate where the hydrodynamic data
were sampled during fin oscillation.
