Acroloxidae, commonly known as river limpets, are a taxonomic family of very small, freshwater molluscs, aquatic pulmonate gastropod limpet-like mollusks with a simple flattened conical shell.

Life habits

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.

Genera in the family Acroloxidae

* "Acroloxus" Beck, 1838
* "Pseudancylastrum"
