Radula | Tongue-like, Teeth-bearing Rasping | Britannica Radula, horny, ribbonlike structure found in the mouths of all mollusks except the bivalves The radula, part of the odontophore, may be protruded, and it is used in drilling holes in prey or in rasping food particles from a surface
What Is a Radula? How Mollusks Use Their Teeth - ScienceInsights A radula is a tongue-like feeding organ found in almost all mollusks, covered in rows of tiny teeth that scrape, rasp, and tear food It’s unique to mollusks (snails, slugs, octopuses, chitons, and their relatives) and exists in no other animal group

Not just scratching the surface: distinct radular motion patterns in . . . The radula is the organ for mechanical food processing and an important autapomorphy of Mollusca Its chitinous membrane, embedding small radular teeth, is moved by the set of muscles resulting in an interaction with the ingesta, tearing it and collecting loosened particles
