Radula | Tongue-like, Teeth-bearing & Rasping | Britannica
网页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. It is supported by a cartilage-like mass (the odontophore) and is.
A Microscopic Look at Snail Jaws - Natural History Museum
网页Snails and slugs eat with a jaw and a flexible band of thousands of microscopic teeth, called a radula. The radula scrapes up, or rasps, food particles, and the jaw cuts off larger pieces of food, like a leaf, to be rasped by the radula.
Not just scratching the surface: distinct radular motion patterns …
网页2020年10月21日 · 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.
What Is a Radula? - ThoughtCo
网页2019年2月9日 · The radula is a special structure used by many mollusks to scrape food off rocks, to feed off of plants or create depressions in rocks that the mollusk uses for habitat. The radula has many rows of tiny teeth that are replaced as they wear down. Each row of teeth consists of marginal teeth, one or more lateral teeth and a median tooth.
Radular structure and function. | The biology of terrestrial molluscs
网页The radula is a special feature of molluscs. It is a cuticular structure of the ectodermal foregut epithelium and is part of the buccal mass, the mollusc feeding apparatus. This paper discusses the anatomy of the buccal mass, radula formation, radula transport, radula function and role of the jaw in gastropods.

网页2021年9月15日 · The radula is the structure used for food processing in Mollusca. It can consist of a membrane with stiffer teeth, which is, together with alary processus, muscles and odontophoral cartilages, part of the buccal mass. In malacology, it is common practice to infer potential tooth functions from morphology.

Radular Morphology and Relationship Between Shell Size and Radula …
网页2022年2月13日 · The radula is the main feeding organ and also very significant to the majority of the mollusks (especially gastropod) taxonomy. With shell morphology, radular morphology is the key characteristic for the identification of gastropod species. The shape and structure of the radular teeth are unique from family to species level.
