Calms have pearls as a natural defense mechanism to protect themselves from irritants, such as parasites or foreign objects. When an irritant enters their body, they secrete layers of nacre, a substance made of aragonite and conchiolin, around it, forming a pearl. This process helps to minimize discomfort and potential harm by isolating the irritant. Pearls can also have value in terms of attraction for reproductive purposes in some species.
