[R4P-02] Texture observation on the calcite-aragonite interface in the skeletons of culturing scleractinian coral
Keywords: reef-building coral, biomineralization
Most scleractinian corals inhabit tropical and subtropical oceans with symbiont algae and have aragonitic skeletons. Calcite, however, has been reported as a skeletal component in corals currently inhabiting the Southern Ocean with low temperatures or in Cretaceous corals that inhabited seas with different chemical compositions. In this study, corals were cultured in conditions where calcite precipitation was induced and the skeletal texture including the interface of calcite and aragonite were observed using a TEM, to reveal polymorph selection in coral calcification.
