The radula of the limpet, Cellana toreuma, consists of a continuous series of teeth in various stages of iron biomineralization. The major iron-binding protein of the limpet's iron-containing granule (siderosome) has been purified and identified as ferritin. Limpet ferritin has a M(r) of 575 kDa and can be resolved into two bands by SDS-PAGE analysis, with respective M(r)s of 26 and 21 kDa. The partial N-terminal amino acid sequences of these two subunits were confirmed, and antisera against… 
Silica Biomineralization in the Radula of a Limpet Notoacmea schrenckii (Gastropoda: Acmaeidae)
Electron-dense granules in a nanometer size range were observed in ultrathin sections of tooth specimens in early mineral-deposition stage; electron diffraction analysis indicated that silica is the primary component of these granules.
The Microstructure, Proteomics and Crystallization of the Limpet Teeth
Insight is provided into the unique biomineralization process in the limpet teeth at the molecular levels, which may guide biomimetic strategies aimed at designing hard materials at room temperature.
Evidence that electron-dense bodies in Cyanidium caldarium have an iron-storage role
The acidophilic and thermophilic unicellular red alga, Cyanidium caldarium (Tilden) Geitler, is widely distributed in acidic hot springs, and it is concluded that iron in the electron-dense bodies accounts for the isotropic ESR signal.

Mineralisation in the teeth of the limpets Patelloida alticostata and Scutellastra laticostata (Mollusca : Patellogastropoda)
The sequence and ultimate pattern of mineralisation in the major lateral radula teeth of two species of limpet, namely Patelloida alticostata and Scutellastra laticostata, have been elucidated using energy dispersive, Raman and infrared spectroscopies, suggesting that the mineralisation of iron and silica is a very ancient character.
From bacteria to mollusks: the principles underlying the biomineralization of iron oxide materials.
The chemical and biological machineries that are involved in controlling mineral precipitation and organization are described and it is shown how these organisms are able to form highly complex structures under physiological conditions.
In slow motion: radula motion pattern and forces exerted to the substrate in the land snail Cornu aspersum (Mollusca, Gastropoda) during feeding
The physical properties of the radular teeth of Cornu aspersum, a large land snail, with experiments revealing their radula scratching force are related, to better understanding functions and adaptations of radulae to ingesta or substrate, and hence, gastropods speciation and evolution.
