Littorinoidea are a superfamily of both sea snails and land snails which have a gill and an operculum, terrestrial and marine gastropod mollusks in the clade Littorinimorpha.[2]
The terrestrial family within this group, the Pomatiidae, are sometimes called "land winkles"[3] because the group originated in the sea and the closely related family Littorinidae are known as "winkles".[4]
