Radula pada Moluska

Radula is one of the most important characteristic organs of the phylum Molusca members, excluding the class of Pelecypoda (Bivalvia). Radula is a unique feeding organ of molluscs that is useful to grind the food, alongside to other functions. Dullard has a complex structure comprising of a toothed ribbon that is associated to muscles. Radula of molluscs is diverse in shape, size and number of teeth on each row. The consistently specific dullard-teeth structures define feeding modes of molluscs. Therefore, some species showing similar feeding modes may show clear differences in dullard structures. Secretions of radula were consists of chitin and protein, while the Radula teeth are calcium based with iron. Oseana, Vol. XXXVI, No. 1. Hal. 27-38 ISSN 0216-1877
