Nacre differs from fibrous aragonite – a brittle mineral of the same form – in that the growth in the c-axis (i.e., approximately perpendicular to the shell, in nacre) is slow in nacre, and fast in fibrous aragonite. Nacre is secreted by the epithelial cells of the mantle tissue of various molluscs. The nacre is continuously deposited onto the inner surface of the shell, the iridescent ""nacreous layer"", commonly known as ""mother of pearl"". The layers of nacre smooth the shell surface and help defend the soft tissues against parasites and damaging debris"
