Abstract
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. In this study, five basic types of radula (i.e., docoglossan, rhipidoglossan, taenioglossan, stenoglossan, and toxoglossan), which were observed from a total of 23 different species belonging to 12 families, were examined. Collection of the voucher intertidal gastropod specimen for the study had initiated during May–October 2019 in the rocky intertidal area near Veraval of the south Saurashtra coastline. Direct handpicking methods were used for the collection of the specimen for experiments.
Highlights
The radula, a unique taxonomical characteristic and feeding organ of mollusks, is found in every class except the class Bivalvia (Arularasan et al, 2011)
The communication was deal with the study of the radular morphology of the selected dominating intertidal gastropod mollusks and found the radular pattern that was made by the combination of different kinds of denticles
The results showed that all selected gastropods were followed by all five basic different types of radular patterns, namely, docoglossan, rhipidoglossan, taenioglossan, stenoglossan, and toxoglossan
Summary
The radula, a unique taxonomical characteristic and feeding organ of mollusks, is found in every class except the class Bivalvia (Arularasan et al, 2011). This ribbon-like structure is found and used to slide on odontophore (another supportive part to radula) in the mouth and supports a variety of different feeding mechanisms. This odontophore is embedded with rows of many tiny denticles or teeth.
