Family of gastropods

Patellidae A group of live Patella vulgata on an intertidal rock Scientific classification Kingdom: Animalia Phylum: Mollusca Class: Gastropoda Subclass: Patellogastropoda Superfamily: Patelloidea Family: Patellidae Rafinesque, 1815 Genera 4 extant genera (see text)

**Patellidae** is a [taxonomic](/source/Taxonomy_(biology)) [family](/source/Family_(taxonomy)) of true [limpets](/source/Limpets), [marine](/source/Marine_(ocean)) [gastropod](/source/Gastropod) [molluscs](/source/Mollusc) in the [superfamily](/source/Family_(taxonomy)) [Patelloidea](/source/Patelloidea).[1] (The superfamily Patelloidea should not be confused with the similar-sounding genus of true limpets *[Patelloida](/source/Patelloida)* which is in the family [Lottiidae](/source/Lottiidae) within the superfamily [Lottioidea](/source/Lottioidea), also part of the [Patellogastropoda](/source/Patellogastropoda).)

The largest known limpet in the world is *[Scutellastra mexicana](/source/Scutellastra_mexicana)* that can reach 35.5 cm (14.0 in) in length.[2]

## Taxonomy

A [cladogram](/source/Cladogram) showing phylogenic relations of Patellogastropoda based on [molecular phylogeny](/source/Molecular_phylogeny) research by Nakano & Ozawa (2007):[3]

Patellogastropoda Lottiidae (including Acmaea and Niveotectura) Pectinodontidae Lepetidae Nacellidae Patellidae Eoacmaeidae

## Genera

There are four extant genera in the family Patellidae:[1]

- *[Cymbula](/source/Cymbula)* H. & A. Adams, 1854

- *[Helcion](/source/Helcion)* Montfort, 1810

- *[Patella](/source/Patella_(gastropod))* [Linnaeus](/source/Carl_Linnaeus), [1758](/source/10th_edition_of_Systema_Naturae)

- *[Scutellastra](/source/Scutellastra)* H. Adams & A. Adams, 1854

There are two exclusively fossil genera:[1]

- † *[Berlieria](https://en.wikipedia.org/w/index.php?title=Berlieria&action=edit&redlink=1)* de Loriol, 1903

- † *[Proscutum](/source/Proscutum)* P. Fischer, 1885

## Human uses

Some limpet species in this family are used as a food source in various countries.[2]

A study of *[Patella caerulea](/source/Patella_caerulea)* found that this limpet reduced the cover of [algae](/source/Alga) and [barnacles](/source/Barnacle) on steel panels suspended in sea water in a commercial port, suggesting that the limpet could be used to inhibit fouling of ship hulls.[4]
