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.)
The largest known limpet in the world is Scutellastra mexicana that can reach in length.
Taxonomy A cladogram showing phylogenic relations of Patellogastropoda based on molecular phylogeny research by Nakano & Ozawa (2007):
Genera There are four extant genera in the family Patellidae: Cymbula H. & A. Adams, 1854 Helcion Montfort, 1810 Patella Linnaeus, 1758 Scutellastra H. Adams & A. Adams, 1854
There are two exclusively fossil genera: † Berlieria de Loriol, 1903 † Proscutum P. Fischer, 1885

Adams, 1854 (junior synonym)
Human uses Some limpet species in this family are used as a food source in various countries.
A study of Patella caerulea found that this limpet reduced the cover of algae and barnacles on steel panels suspended in sea water in a commercial port, suggesting that the limpet could be used to inhibit fouling of ship hulls.Safriel U. N. & Erez N. 1987. Effect of limpets on the fouling of ships in the Mediterranean. Marine Biology, 95(4): 531-537.
