"Acroloxus lacustris", or the lake limpet, is a small freshwater limpet or snail, a species of aquatic gastropod mollusk in the family Acroloxidae.

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 as, in their non-tidal habitat, these limpets never reach the surface for air.
