- Аннотация: Development of the limpet Testudinalia testudinalis collected from the White Sea was studied usinglight and scanning electron microscopy. Cleavage and early development of T. testudinalis wereconsistent with the general pattern of patellogastropod development, differing in only minordetails, such as temperature-dependent developmental rates. A pre-torsional veliger radula wasdetected by calcofluor white staining of unpolymerized chitin. The veliger radula consisted of ninetransverse rows with three teeth per row, which transformed into the radula of newly settledjuveniles with five teeth per row (one central and two pairs of lateral teeth). The juvenile radula,with two pairs of lateral and one pair of hook-like marginal teeth, resembled the adult radula interms of teeth form and co-localization. Radula formation differs between the larva and adult inthat each tooth is formed by several odontoblasts and microvillar secretion in the former, whereasit is formed by numerous cells and apocrine secretion in the latter.
