Fig. 5. Dorsal, lateral and ventral views of a yawing maneuver to the right at the point of maximum fin excursion. Both dorsal and anal fins show displacement of their trailing edges during this maneuver. Curvature of fin surfaces is large, but the actual bending of each individual fin ray is small. Note that both dorsal and anal fins move to the same side of the fish. Bars, 1 cm.
