Lanistes is a genus of freshwater snails which have a gill and an operculum, aquatic gastropod mollusks in the family Ampullariidae, the apple snails. [7]

Contents

Distribution

The distribution of the genus Lanistes includes Africa and Madagascar. [3]

Description

Lanistes has a unique anatomy among the Ampullariidae: it has a "hyperstrophic" sinistral shell. [8] This means that the body of the snail is dextral (as in all other ampullariids), but the shell appears to be sinistral. [8] However the sinistral appearance stems from the fact that the rotation of the shell as it grows is in an upward direction rather than the usual downward direction. [8]

Species

Three [3] subgenera have been recognized, based on shell differences: Lanistes sensu stricto, Meladomus and Leroya. These subgenera are not used in recent works. [3]

Extant species within the genus Lanistes include:
