One lineage of the Ellobioidea, the Carychiidae has successfully accomplished a complete transition onto land. Extant carychiid snails inhabit aphotic and permanently wet epigean or subterranean environments throughout their Holarctic distribution. This dramatic shift from a marine to a terrestrial habitat has occurred independently of the stylommatophoran land-snails of the Eupulmonata.
