Skeletal morphology of spats imaged using X-ray μCT

Left column: 3D rendering of the skeleton (top-view); middle column: z-projected thickness distribution (expressed as percentage, each spat’s skeleton, n = 1 per treatment, was normalized to its own 100%); right column: local thickness distribution (expressed as μm, the thickness was projected onto a cross-sectional slice of the skeleton and normalized to the highest value reached across the 4 experimental conditions). Rows show the skeleton of spats from 5 m deep grown under experimental light conditions simulating the shallow (SS) or deep reef (SD) and of spats from 45 m deep grown under experimental light conditions simulating the deep (DD) or shallow reef (DS). All scale bars are 300 μm.
