Interspecific comparison of the dorsal scale geometries among ten chiton species. a The phylogenetic distribution of the chiton species used in this study. Variations of morphological parameters, b volume, c length and area ratios, and d angles for different species. The solid line represents the average and the shaded area shows the standard deviations (N = 5 for each measurement). e μ-CT data-based 3D reconstructions of individual dorsal scales from the ten chiton species in four different views: top, bottom, front, and side. All the reconstructions are at the same length scale except those from Rhyssoplax polita.
