Regression shape changes (above) and PCA (below) of Procrustes coordinates for the five analogue species. These are recorded in the (a) head, (b) pectoral fin, (c) dorsal fin, and (d) caudal fin. In the regression analyses, light and dark grey configurations represent the morphological change occurring from the average shape towards higher scores, considering in all cases a magnitude of the shape change equal to 0.1. Individual colours represent each species in the PCA: green = Carcharodon carcharias; yellow = Isurus oxyrinchus; blue = Isurus paucus; orange = Lamna ditropis; red = Lamna nasus.
