Preliminary survey on classification of radula in certain Gastropods of the Persian Gulf (sub-order Prosobranchina

The radula has various shapes and structures in gastropods, which make it possible to distinguish them up to the level of species. In this survey, Iamels and film slides have been prepared from denticulated structure of radula in gastropods of Prosobranchia suborder. The specimens were stained by Gimsa dye with the explained method, which is very effective in identification and classification of the mollusks. After the above mentioned stages, the specimens were examined and compared by light microscope. By use of this method, some of the gastropods including Trochidae, Patellidae, Neritidae, and ... which were collected from tidal coasts of Bandar Lengeh, were identified to the levels of family, or genus. Therefore, it Is concluded that this staining method can be used for some of the mollusks having complex radulas, to be identified and classified easily to the species level......
