Crepipatella dilatata (Lamarck, 1822) (Calyptraeidae): An example of reproductive variability among gastropods
Reproductive characteristics of a species are often defined from a small number of individuals collected from a single location at one particular time. However, this study reveals that the South American gastropod Crepipatella dilatata (Lamarck, 1822) shows an unusually high level of intraspecific v...

Reproductive characteristics of a species are often defined from a small number of individuals collected from a single location at one particular time.
