FIG. 14. — A, the two first axes of a PCA performed on the harmonics of Fourier for the ventral view; B, the same for the apical view; C, D, location of the the populations means in the canonical space corresponding to the amplitudes of the harmonics of Fourier for the apical view; C, the two first canonical axes CA1 versus CA2; D, canonical axes CA1 versus CA3; green triangle, Moroccan Atlantic; yellow triangle, Cap Rhir; green square, Oualidia (O. brevirobusta). Red group, Mediterranean forms (Ocenebra erinaceus (Linnaeus, 1758)); blue group, North Atlantic forms (O. erinaceus); green group, Moroccan Atlantic forms (O. brevirobusta Houart, 2000), black square (Ocinebrellus inornatus (Récluz, 1851)).
