Bythinellidae

Bythinellidae is a family of small freshwater snails with an operculum, aquatic gastropod molluscs in the order Littorinimorpha.

Their minute shell is often colored. They are characterized by a calcareous operculum, a lobe on the upper surface of the neck. The ctenidium, the respiratory gill-comb, is very broad. They have a ciliary feeding habit. The kidney has a large extension towards the mantle.
