| Ancylus fluviatilis O. F. Müller, 1774 |
Ancylus fluviatilis is a species of very small, freshwater, air-breathing limpet, an aquatic pulmonate gastropod mollusk in the family Planorbidae. (It is sometimes classified in its own family, the Ancylidae).
This freshwater limpet is rheophile (it lives in fast running waters).
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.
