Overview Afropomus Asolene Felipponea Lanistes Marisa Pila Pomacea Saulea

The african genus Lanistes (Montfort, 1810) contains 21 species.
The type species is Lansites carinatus (Olivier, 1804).
A distinguishable feature of the Lanistes genus is the sinistral shell (the shell is turned to the left), while the body is dextral. This paradox is called hyperstrophic sinistral.
