Fig. 8. Lift coefficients C_L (A), drag coefficients C_D (B), and pitching moment coefficients about the center of mass C_M (C) for four boxfishes (smooth trunkfish, buffalo trunkfish, scrawled cowfish and spotted boxfish) positioned at various pitch angles. In A, C_L values for a delta wing of similar aspect ratio (0.83) to that of the boxfishes are also depicted. Delta wing data are from Schlichting and Truckenbrodt (1969), and smooth trunkfish data are from Bartol et al. (2003). Positive C_M values indicate a nose-down pitching moment about the center of mass, whereas negative C_M values indicate a nose-up pitching moment about the center of mass.
