Abstract: The increase of the whorls in the species of Planorbarius corneus L. and Anisus septemgyratus Rossm. is roughly exponential. The growth of P. corneus comprises one phase only, that of A. septemgyratus can be divided into a rapid and a slow period. In the species of Chondrula tridens O. F. Müller the tooth variation of strong H3, G3 and week B is quite frequently found. There is almost a direct ratio between the shell elongation and height. In studying the changes of form of Unio shells the functionality established between the elongation and the lenght can be applied.Subject: zoology
