Fig. 8. (A) Relative body thickness (mean ± S.E.M.) of five leopard sharks as a function of axial position. To compare individuals of different sizes, body thickness is normalized to thickness measured at 0.3 L. Thickness measurements were made from dorsal video images. (B) Dorsal midline curvature calculated for six positions along the body in eight leopard sharks swimming 1.0 L s^–1. Values are means ± S.D. calculated from four tailbeat cycles for each fish at each body position.
