Fig. 4. Mean maximum excursion vs swimming speed. Maximum excursion
increases with swimming speed. During steady swimming the dorsal fin (red) has
larger excursions than the anal fin (blue) and both fins have greater
excursions than the body (black). Unsteady maneuvers have highest maximum
excursions and variation. Values are means ± 1
S.E.M. of all fish (N=4).
