Scleractinian coral skeleton is one of the central keys to determining scleractinian evolution and classification. And it is increasingly applied to reconstructing past ocean and climate histories and to predicting future impacts of climate change and ocean acidification on coral reefs. To better understand skeletogenesis and microstructure in extant scleractinian corals, we analyzed the microstructure and composition of common reef-building coral Pocillopora damicornisfrom Sanya using Scanning Electron Microscope (SEM) and infrared spectroscopic methods. The results revealed that the skeletons were predominantly comprised of aragonite, with limited calcite. The macro- and meso-architectures varied between colonies and corallites. There were several types of skeletons, which had distinct morphology but shared the same basic structure and growth pattern. The occurrence of cements, which combined with the secondary aragonite and brucite in the inter-septal zone, were associated with habitats and micoborings.
