As in all molluscan groups except the bivalves, gastropods have a firm odontophore at the anterior end of the digestive tract. Generally, this organ supports a broad ribbon (radula) covered with a few to many thousand “teeth” (denticles). ... Radular morphology is an important tool for species identification.
What does a radula look like in a gastropod?
As for the radula itself. it is a ribbon-like structure covered with many denticles (tiny teeth). It is movable over the odontophore and is also controlled by muscles. The feeding behavior of marine snails include some that are herbivores, detritus (debris) feeders, scavengers and predatory carnivores.
What is the function of the radula in gastropods?
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.
