Aragonite forms naturally in almost all mollusk shells, as well as the calciferous exoskeletons of warm- and cold-water corals. Because the mineral deposition in mollusk shells is strongly biologically controlled, some crystal forms are distinctively different from those of inorganic aragonite. In some mollusks, the entire shell is aragonite; in others, aragonite forms only discrete parts of a bimineralic shell (aragonite plus calcite).
