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]
Anatomy
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
Species in the genus Rhodacmea include:
- Rhodacmea elatior (Anthony, 1855) - Domed ancylid[4]
- Rhodacmea filosa (Conrad, 1834) - Wicker ancylid,[5] type species[1]
- Rhodacmea hinkleyi (Walker, 1908)[2]
