The Rocky Mountain capshell, Acroloxus coloradensis, is a very small, freshwater limpet or snail, a species of aquatic gastropod in the family Acroloxidae. It is endemic to the United States.
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.
