Fig. 5. The box plot of abundance of all crab species with carapace width larger than 10 mm for three factors: A: season; B: tidal and sampling time; C: study site and sampling time. The gray bar is daytime; the dark gray bar is night. The high tidal level is the edge between the sand and reef; the medium tidal level is at the algal reef 1 m below sea level.

<p>001-Secretanella_sp_AAK_072019.zip - µCT scan data, 1.28 GB stack of DICOM images. High-resolution X-ray computed tomography (CT) scans of specimen ALMNH:Paleo:6522 were obtained at the Berkeley Preclinical Imaging Facility (UC Berkeley, California, USA) in July 2019 using a GE Healthcare eXplore Locus Micro CT Scanner. The specimen was scanned using a conebeam energy of 80 kV, a current of 450 µA, 2,000 ms exposure time, and no filter, resulting in a voxel resolution of 20.523 µm. Visualization and three-dimensional reconstruction of the resulting µCT data were performed using the open-source software 3D Slicer v.4.13.0 (Fedorov et al., 2012).</p> <p>Additional_images_gifs_3Dmodel.zip - archive containing 3 folders of additionnal images, video (gifs) and a 3D model (STL file) :</p> <p>- Addendum_Figure_3 : additional images / views to the figure 3 presented in the paper.</p> <p>- Gifs_3d_models : gifs and STL 3d model of the scanned specimen</p> <p>- Images_gifs_inc_gastric_musc : images, gifs and 3d model similar as in the other folders, but displaying potential gastric muscles</p>
