The radula (US: / ˈ r æ dʒ ʊ l ə /; pl.: radulae or radulas) [1] is an anatomical structure used by mollusks for feeding, sometimes compared to a tongue. [2] It is a minutely toothed, chitinous ribbon, which is typically used for scraping or cutting food before the food enters the esophagus .
The buccal mass is the first part of the digestive system, and consists of the mouth and pharynx. The mouth includes a radula, and in most cases, also a pair of jaws. The pharynx can be very large, especially in carnivorous species. Many carnivorous species have developed a proboscis, containing the oral cavity, radula, and part of the ...
Median – Middle, as the middle tooth on the radula. [1] Mesocene – The middle cusp on the teeth of the radula. [1] Monoecius – Having the sexes united in the same individual. [1] Multifid – Made up of many lobes or projections, as the cusps on some radulae. [1] Multispiral – Consisting of many whorls, as some fresh-water snails. [1]
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] The radula is found in every class of molluscs except for the ...
The radula in this species is longer than the shell itself. It contains 1,920 teeth in 160 rows of 12 teeth each. Patella vulgata is found attached to firm substrates from the high shore to the edge of the sublittoral zone, although it predominates in areas of wave action. Its shell is conical, up to around 6 cm long, and lacks defined chirality.
The radula is taenioglossate, consisting of seven teeth per row: one middle tooth, flanked on each side by one lateral and two marginal teeth. The radula is used to scrape algae and detritus. Phlorotannins in the brown algae Fucus vesiculosus and Ascophyllum nodosum act as chemical defenses against L. littorea .

The rosy wolfsnail is specialized for carnivory, its buccal mass being totally contained within a beak-like rostrum that can be extended, thus allowing the toothed radula to be ejected past the mouth and into the snail's prey. The radula is enlarged and has teeth specialized into elongated cones.
