"Ferrissia fragilis" is a species of small freshwater limpet, an aquatic gastropod mollusk in the family Ancylidae, (sometimes placed in the family Planorbidae or Ferrisiidae).

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.
