Figure 1. Body shapes of pelagic Myliobatiformes are expanded to show familial differences in head shape. The two main phylogenetic hypotheses (see text for references) concerning the myliobatoids are reported on both sides: according the first one (A), more derived myliobatoids possess more enlarged cephalic lobes (shaded grey), according the second one (B), more derived myliobatoids possess a complete fusion of cephalic lobes.
