Figure 2 Examples of shell parameters measured from 2D slices of micro-CT scans. Measurements include A apical angle B larval shell height C maximum larval shell width, and D maximum adult shell diameter. The position of the slice through the 3D model to create a 2D image is shown in E relative to the suture.
