Figure 4


Fig. 4. Posterior, dorsal and ventral views of maneuvering behaviors in bluegill sunfish. (A) Posterior view during a braking maneuver. Note the asymmetry of the caudal fin. The caudal edge of the dorsal fin is curled forward into the flow. Image courtesy of Brooke Flammang (unpublished data). (B,C) Dorsal and ventral views of a right turning maneuver. Both dorsal and anal fins show displacement of their trailing edges during this maneuver. Curvature of the fin surfaces is large, but the actual bending of each individual fin ray is small. Scale bars throughout are 1 cm (from Standen and Lauder, 2005).
