Supplementary File 2 - Full-shell morphospace

Supplementary File 2 – Morphospace plot of all hard-shelled species utilized in this study, calculated from full shell data generated by reflecting all non-midsagittal landmarks across the midsagittal plane. Data are color-coded by Family. Wireframe images outside of the corners of plots indicate shapes associated with those regions of morphospace (e.g., images outside the upper right corner indicate shapes associated with high PC1 and PC2 scores). The matrix correlation between species’ scores on the first two PCs of the half-shell analysis and species’ scores on the first two PCs of the whole-shell analysis was 0.926. The matrix correlation between Procrustes distance matrices for the half-shell and whole-shell analyses (with distances in each matrix calculated between species) was 0.982.
