Patellidae is a taxonomic family of true limpets, marine gastropod molluscs in the superfamily Patelloidea.
(The superfamily Patelloidea should not be confused with the similar-sounding genus of true limpets Patelloida which is in the family Lottiidae within the superfamily Lottioidea, also part of the Patellogastropoda.)
Patellidae
Limpets are a group of aquatic snails with a conical shell shape (patelliform) and a strong, muscular foot. This general category of conical shell is known as "patelliform" (dish-shaped). Existing within the class Gastropoda, limpets are a polyphyletic group.
