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

Anatomy

edit

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.
