Figure 4

Overview chart showing analyzed specimens of irregular sea urchins and corresponding 3D reconstructions of selected internal organs. (A) Information on species name, geographic distribution, and systematics. (B) Photograph of scanned specimen, aboral view. (C)-(E) 3D models of reconstructed selected internal organs, stepwise turned by 90°: (C) aboral view (ambulacrum III facing to the right); (D) lateral view (ambulacrum III facing to the right); (E) oral view (ambulacrum III facing to the right). Scale bar: 1 cm, except for Echinocyamus pusillus: 1 mm. The colour legend specifies organ designation.
