Raw data for time lapse scores

Supplementary Table 1. Data from analysis of time lapse series, showing number of frames in each a priori position in each experiment. The mean percentage time per trial for "ball", "arching" and other positions is illustrated in Figure 1. Each time lapse recorded lasted for 2 h. Statistical analyses used total number of frames (time) scored per position. Summary data presented in this spreadsheet include the calculations for percent time in all trials and raw text data from scored frames in each video

Video_S1_Cryptometamorphosis

Video S1. A video illustrating a hypothesised scenario of isometric growth post-settlement in Gigantopelta chessoia versus the observed cryptometamorphosis, showing changes in the anatomy of the digestive system around the point of transition (3.5 mm to 12.2 mm body length). Simulated growth and rendering was done in Blender v2.79b

Sumner-Rooney et al. S3

Arm segments from Ophiocoma pumila. The 3D data included here were generated from x-ray tomography scans of specimens of brittle stars Ophiocoma wendtii, Ophiocoma echinata and Ophiocoma pumila. For full methodology, please refer to the Method Details text. All models are downsized for practicality in PDF form; STL files with full detail are available on request. 3D files require Adobe Acrobat or Acrobat Reader (v. 7 or higher) for full interactive functionality. Use left-click to rotate, Ctrl+click to pan, and shift+click to zoom. Default view is the dorsal surface
