Minerals have been found in the radular teeth of molluscs from the classes Caudofoveata, Polyplacophora, Monoplacophora, and Gastropoda (Patellogastropoda: Acmaeidae, Patellidae). Here we report the discovery of amorphous iron oxide and hydroxyapatite in the highly modified radular apparatus of Falcidens sp. (Caudofoveata). The mineralization process in Falcidens sp. is unique: the components of the radular apparatus, unlike those of other molluscs, are not renewed during the animal's lifetim...

Minerals of the radular apparatus of Falcidens sp. (Caudofoveata) and the evolutionary implications for the phylum Mollusca. The Biological Bulletin ; Introduction The radula is one of the most characteristic organs of the phylum Mollusca, lacking only in the class Bivalvia. The function of the radula is to obtain food. The basic pattern of most radulae consists of several to numerous transverse rows of radular teeth with bilateral symmetry
