Hebetancylus is a genus of small, freshwater, air-breathing limpets, aquatic pulmonate gastropod molluscs in the family Planorbidae, the ram's horn snails and their allies. [1]
These animals have a pallial lung, as do all pulmonate snails, but they also have a false gill or " pseudobranch" which can serve perfectly well as a gill when they are unable to reach the surface for air.
Species within the genus Hebetancylus include: [2] [3]
