... 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...

...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...

... and digitization of a desired object in both images, and reduced digitizing error. Excursion of dorsal and anal fins (mm) was calculated by digitizing the tip of the fin ray at the trailing edge of each fin. Body excursion (mm) was calculated by digitizing the posterior attachment point of the dorsal fin...

...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...
