| Abstract |
Prior studies have shown different insights about sexual shell dimorphism in the snails of family Viviparidae. This study was conducted to evaluate and determine the occurence of sexual dimorphism and shape variation in the shells of the viviparid snail, Vivipara angularis Muller, from three characters (ventral/aperture, dorsal, and top/whorl) using geometric morphometric analyses. All the three shell characters
exhibited significant sexual shell dimorphism, this may be due to adaptations for brooding of the viviparid snails. Results indicate employment
of different shell characters subjected to geometric morphometric analysis other than the aperture, in order to discriminate between sexes of
the snails accurately. |
