PIC maps of the 5 coral species that exhibit few or no sprinkles. These are Turbinaria peltata (Tp), Stylophora pistillata (Sp), Porites lutea (Pl), Montipora turgescens (Mt), and Micromussa lordhowensis (Ml). Again centers of calcification (CoCs, between pairs of CoC labels) are distinguishable by their nanoparticulate appearance along a straight line in Tp, a long tortuous line in Sp, four parallel lines in Pl only one of which is between CoC labels, and in Mt. As in Figure 4, none of these CoCs exhibit any sprinkles. Arrows indicate the very few visible sprinkles. These are so few that they could belong to out-of-plane bundles of fibers, thus these 5 species are described as non-sprinkle retaining.
