Water Vascular System

Raw STL triangular mesh of P. flexuosa water vascular system used in Maya model. See legend of figure 2 in the main text of publication for details

Scan B: Protasterina flexuosa (CMC 25001)

Micro-CT scan of Protasterina flexuosa (CMC 25001) using a Nikon XTek XT H225 scanner (Tokyo, Japan). 3200 two-dimensional images were generated with a voxel size of 6.0 microns at a voltage of 85 kV and current of 90 microamps. Volume was reconstructed using Nikon CTPro 3D (Tokyo, Japan). Users should contact authors prior to file use other than corroborating data presented in paper

Scan C

Micro-CT scan of Protasterina flexuosa (CMC 25001) using a Nikon XTek XT H225 scanner (Tokyo, Japan). 3200 two-dimensional images were generated with a voxel size of 10.4 microns at a voltage of 85 kV and current of 90 microamps. Volume was reconstructed using Nikon CTPro 3D (Tokyo, Japan). Users should contact authors prior to file use other than corroborating data presented in paper

Scan A: Protasterina flexuosa (CMC 25001)

Micro-CT scan of Protasterina flexuosa (CMC 25001) using the North Star Imaging micro-CT scanner housed at Vanderbilt University (Tennessee, USA). 1170 two-dimensional images were generated with a voxel size of 29.3 microns at a voltage of 100kV and current of 62 microamps. Volume was reconstructed using EFX-CT. Users should contact authors prior to file use other than corroborating data presented in paper
