... of fish locomotion are misleading. In this study, we first examine axial swimming from the two-dimensional viewpoint, detailing the limitations of this view. Then we present data on the kinematics and hydrodynamics of the dorsal fin, the anal fin and the caudal fin during steady swimming and maneuvering...

...E. M. Standen; G. V. Lauder SUMMARY Recent kinematic and hydrodynamic studies on fish median fins have shown that dorsal fins actively produce jets with large lateral forces. Because of the location of dorsal fins above the fish's rolling axis, these lateral forces, if unchecked, would cause fish...

... along the body is shown in Fig. 1E , based on that in Jenkins and Burkhead ( Jenkins and Burkhead, 1994 ). Streamwise vortices are shed from the soft dorsal fin along its dorsal margin (termed `outer edge') and along the free ventral margin (`inner edge'). Equivalently, from the anal fin, vortices...

...Eliot G. Drucker; George V. Lauder SUMMARY In this study, we examine the kinematics and hydrodynamics of the soft dorsal fin in a representative basal teleost, the rainbow trout( Oncorhynchus mykiss ), during steady rectilinear locomotion at 0.5–2.0 body lengths ( L ) s –1 and during maneuvering...

... curvature occurring in individual fin rays. Fin ray curvature may also be reduced by normal pressures on the fin caused by water flow. For example, in Fig. 5 , dorsal fin surface is deformed to lie 90° to the direction of the water flow. The normal pressure of the water on the surface of the fin may...

...Erin M. Meagher; William A. McLellan; Andrew J. Westgate; Randall S. Wells; Dargan Frierson, Jr; D. Ann Pabst SUMMARY The dorsal fin of the bottlenose dolphin Tursiops truncatus contains blood vessels that function either to conserve or to dissipate body heat. Prior studies have demonstrated...

...Eliot G. Drucker; George V. Lauder SUMMARY A key evolutionary transformation of the locomotor system of ray-finned fishes is the morphological elaboration of the dorsal fin. Within Teleostei, the dorsal fin primitively is a single midline structure supported by soft, flexible fin rays. In its...
