A shelled mollusc gets irritated when a microscopic or small organism enters its mantle folds. Generally, the parasites gain access to the soft mantle tissue when the shell valves remain open to eat or respire. In the form of defence mechanism, a mollusc forms a pearl sac and releases calcium carbonate and conchiolin repetitively; resulting in pearl to shield itself against the unwelcomed irritant. The calcium carbonate produced in the pearl sac as mineral aragonite is held together by conchiolin, this combination is known as nacre or mother of pearl.
