Patellidae is a taxonomic family of true limpets, marine gastropod molluscs in the superfamily Patelloidea.^[1] (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 35.5 cm (14.0 in) in length.^[2]

Human uses

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

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.^[4]
