Flexural rigidity measured for the biological fin rays (points), scaled 1000 times, and fitted by models of fin rays (lines; see text for discussion of how flexural stiffness of the biological fin rays was measured and scaled for the robotic fin) that tapered independently in width and thickness. Flexural rigidity measured for the biological fin rays (points), scaled 1000 times, and fitted by models of fin rays (lines; see text for discussion of how flexural stiffness of the biological fin rays was measured and scaled for the robotic fin) that tapered independently in width and thickness. Note that flexural rigidities of the sunfish fin rays vary considerably along the length of each fin ray and across the fin. Rays 1 and 2 (the dorsal-most rays) are closely attached and were treated as a single element. James L. Tangorra et al. J Exp Biol 2010;213:4043-4054 © 2010.
