Key Identification Features
- Members of the genus Cipangopaludina can be identified by their relatively large globose shells and concentrically marked opercula.
- In juveniles, the final whorl has a distinct carina, and the shell has grooves with 20 striae per millimeter between each groove.
- In 1863, Émile Baudelot clearly stated that paludines (river snails) have two distinct sexes.
- Males can be distinguished by a shorter right tentacle with a rounded tip, which also acts as a penis during fertilization.
