American Heritage® Dictionary of the English Language, Fourth Edition
- n. A flexible tonguelike organ in certain mollusks, having rows of horny teeth on the surface.
Century Dictionary and Cyclopedia
- n. In conchology, the tongue or lingual ribbon of a mollusk, specifically called odontophore, and more particularly, the rasping surface or set of teeth of the odontophore, which bites like a file. This structure is highly characteristic of the cephalophorous classes, among which it presents great diversity in detail. It bears the numerous small chitinous processes or teeth of these mollusks, which serve to triturate food with a kind of filing or rasping action. According to the disposition of the teeth in any one of the many cross-rows which beset the length of the radula, mollusks are called rachiglossate, tænioglossate, rhipidoglossate, toxoglossate, ptenoglossate, and docoglossate. See these words, and odontophore.
GNU Webster's 1913
- n. (Zoöl.) The chitinous ribbon bearing the teeth of mollusks; -- called also

“All gastropods feed by using a radula, which is a tongue-like structure covered by rows of rasping teeth.”
“Snails and slugs do have teeth on an organ called radula that are sharp enough to cut thru plant tissue.”
“After tearing apart food with a chitinous tongue called the radula, their food travels down the gullet.”
“After tearing apart foot with a chitinous tongue called the radula, their food travels down the gullet.”
“Some of the tracks were very clear: one could see the marks the teeth on the radula left as the slug was scraping off its food, cyanobacteria growing on the bark.”
“This one reveals the marks of the individual teeth of the radula that does the scraping.”
“I would be intriguing to see where they concentrate on feeding, if they have any hidey-holes higher in the tree, if there is a difference in slug body size as related to radula scrape size in height along the tree, etc.”
“There are isolated groves of the rare endemic Kamchatkan fir Abies gracilis, also Sakhalin fir Abies sachalinensis, unusual thermally influenced caldera communities and several nationally threatened plants such as Cypripedium macranthon, Carex viridula, Fimbristylis ochotensis, Isoetes asiatica, Poa radula and Rhodiola rosea.”
“The buccal mass is where the radula resides and the ring-like organ immediately below it and encircling the esophagus may be called the snail's brain, for that's where all the nerves coming from different corners of the snail's body congregate.”
“However, even waterproof inks can be scraped off, for example, by the radula of another snail.”
