Rhodacmea is a genus of small freshwater snails or limpets, aquatic gastropod mollusks in the family Planorbidae, the ram's horn snails and their allies. [2]
Rhodacmea is the type genus of the subfamily Rhodacmeinae. [3]
These animals have a pallial lung, as do all pulmonate snails, but they also have a false gill or "pseudobranch". This serves as a gill, which is necessary as, in their non-tidal habitat, these limpets never reach the surface for air.
Species in the genus Rhodacmea include:
Ferrissia neozelanica, also known as Gundlachia neozelanica, is a species of minute freshwater limpet, an aquatic pulmonate gastropod mollusk, or micromollusk, in the family Planorbidae.
Burnupia is a genus of small freshwater snails or limpets, aquatic gastropod mollusks that are traditionally placed in the family Planorbidae.
Conus africanus, common name the African cone, is a species of predatory sea snail, a marine gastropod mollusk in the family Conidae, the cone snails, cone shells or cones.
Elimia ampla, common name ample elimia, is a species of freshwater snail with a gill and an operculum, an aquatic gastropod mollusk in the family Pleuroceridae.
