Radular teeth development and wear in Allaegopis spec. A (Gastropoda Pulmonata: Zonitidae)

The radula of a specimen of Allaegopis spec. A was studied. Some detailed photographs could be made, illustrating that many rows of young teeth cannot function because they are not yet fully developed, whereas many rows at the opposite end of the radular ribbon are eroded, the last ones to such an extent that they cannot possibly fulfil a scraping function optimally any more.
