Fig. 9. Pressure coefficients (C_P) plotted as a function of location (pressure port) along various dorso-ventral transects on the smooth trunkfish model positioned at positive pitching angles of attack. The locations of the pressure ports included in each graph are highlighted in images of the model. Note pressure ports A2, A4 and A6 are located in the middle of the ventral region of the carapace, which is not visible in the images. The dorso-ventral transects considered are: (A) eye ridge, (B) maximum girth, (C) midpoint between maximum girth and the posterior edge of the carapace and (D) posterior edge of the carapace. Values are means ± 1 S.D.
