The Littorinidae are a taxonomic family of over 200 species of sea snails , marine gastropod molluscs in the clade Littorinimorpha , commonly known as periwinkles and found worldwide.
In English-speaking countries, gastropod molluscs from other families, such as the Neritidae , are sometimes also commonly known as "winkles" because they are small, round snails that occupy a similar ecological niche.
These subfamilies have been recognized in the taxonomy of Bouchet & Rocroi (2005):
