Rhodacmea is the type genus of the subfamily Rhodacmeinae.[3]
Anatomy
editThese 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
editSpecies 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]
