A typical radula comprises a number of bilaterally-symmetrical self-similar rows of teeth rooted in a radular membrane in the floor of their mouth cavity. Some species have teeth that bend with the membrane as it moves over the odontophore, whereas in other species, the teeth are firmly rooted in place, and the entire radular structure moves as one entity.

Drawing of selected radular teeth of Clappia umbilicata: central tooth, lateral tooth, inner marginal tooth and outer marginal tooth. Somatogyrus umbilicatus n. sp. Pl. v, fig. 5. Shell small, globosely depressed, umbilicate, light greenish-yellow, smooth, except for the fine, rather unequal, lines of growth. Spire short, obtusely elevated.
The food is shown in blue. Muscles that control the radula are shown in brown. The surface of the radula ribbon, with numerous teeth, is shown as a zig-zag line. The odontophore is part of the feeding mechanism in molluscs. It is the cartilage which underlies and supports the radula, a ribbon of teeth. [1]
Unlike other Aeolidida, the family Aeolidiidae possesses radular teeth which aid in feeding on their prey (See Fig. 2). [7] The radula is a feature in majority of mollusks located in the mouth, like a tongue, containing thousands of teeth that help cut up food for digestion by scraping against rocks or even Fig. 2 A. papillosa Radular Teeth
In paleontology, denticle characteristics such as size and density (denticles per unit distance) are used to describe and classify fossilized teeth, especially those of dinosaurs. Denticles are also present on the teeth of varanoid lizards, sharks, and mammals. [1] The term is also used to describe the analogous radular teeth of mollusks. [2 ...
