Fig. 2From: New insights into the evolution of portunoid swimming crabs (Portunoidea, Heterotremata, Brachyura) and the brachyuran axial skeletonRepresentations of three-dimensional (3D) data from the axial skeletons of outgroup taxa of Heterotremata. A Calappidae (Calappoidea), 3D model is supplied in Additional file 5, B Matutidae (Calappoidea), 3D model is supplied in Additional file 6, C, D Cancridae (Cancroidea), 3D models are supplied in Additional files 7, 8, E Corystidae (Corystoidea), 3D model is supplied in Additional file 9, F Cheiragonidae (Corystoidea), 3D model is supplied in Additional file 10.
