Fig. 1From: 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 Podotremata and Thoracotremata. A Dromiidae (Podotremata), 3D model is supplied in Additional file 2, B, C Varunidae (Thoracotremata), 3D models are supplied in Additional files 3, 4. Each taxon is also represented by an image showing the cephalothorax with right 5th pereiopod in dorsal view.
