Limpets are a group of aquatic snails that exhibit a conical shell shape (patelliform) and a strong, muscular foot. Limpets are members of the class Gastropoda, but are polyphyletic, meaning the various groups called "limpets" descended independently from different ancestral gastropods. This general category of conical shell is known as "patelliform" (dish-shaped). All members of the large and ancient marine clade Patellogastropoda are limpets. Within that clade, the members of the Patellidae family in particular are often referred to as "true limpets".
The Patellogastropoda, common name true limpets and historically called the Docoglossa, are members of a major phylogenetic group of marine gastropods, treated by experts either as a clade or as a taxonomic order.
Lottia is a genus of sea snails, specifically true limpets, marine gastropod mollusks in the subfamily Lottiinae of the family Lottiidae, one of the families of true limpets.
Fissurellidae, common name the keyhole limpets and slit limpets, is a taxonomic family of limpet-like sea snails, marine gastropod molluscs in the clade Vetigastropoda. Their common name derives from the small hole in the apex of their cone-like shells. Although superficially resembling "true" limpets, they are in fact not closely related to them.
Patellidae is a taxonomic family of sea snails or true limpets, marine gastropod molluscs in the clade Patellogastropoda.
Cellana sandwicensis, common name the yellow-foot ʻopihi, is a species of edible true limpet, a marine gastropod mollusc in the family Nacellidae, one of the families of true limpets.
Cellana exarata, common name the black-foot ʻopihi and Hawaiian blackfoot is a species of edible true limpet, a marine gastropod mollusc in the family Nacellidae, one of the families of true limpets. ‘Opihi are significant in Hawaiian history where they have had many uses such as food, tools, and jewelry. They are known as a “fish of death.”
Lottioidea is a superfamily of sea snails or limpets, marine gastropod mollusks in the clade Patellogastropoda, the true limpets.
Cellana talcosa, the talc limpet or turtle limpet is a species of true limpet, a marine gastropod mollusc in the family Nacellidae, which is one of the true limpet families.
Acmaea mitra, common name the whitecap limpet, is a species of sea snail or true limpet, a marine gastropod mollusc in the family Acmaeidae, one of the families of true limpets.
Eoacmaea is a genus of sea snails or true limpets, marine gastropod mollusks in the subclass Patellogastropoda, the true limpets.
Cymbula safiana, common name the saffian limpet, is a species of sea snail, a true limpet, a marine gastropod mollusk in the family Patellidae, one of the families of true limpets.
Eoacmaea albonotata is a species of sea snail, a true limpet, a marine gastropod mollusk in the family Eoacmaeidae, one of the families of true limpets. The species is found off Natal, South Africa.
Lottia mesoleuca is a species of sea snail, a true limpet, a marine gastropod mollusk in the family Lottiidae, one of the families of true limpets.
Patella ferruginea, commonly known as the ribbed Mediterranean limpet, is a species of sea snail, a true limpet, a marine gastropod mollusk in the family Patellidae, one of the families of true limpets. It is a large limpet, native to the western Mediterranean Sea, and although common in the past, it is now rare and restricted to only a few locations.
Patella rustica, the Lusitanian limpet or rustic limpet is a species of sea snail, a true limpet, a marine gastropod mollusk in the family Patellidae, one of the families of true limpets. It is a rocky shore intertidal mollusc found throughout the Mediterranean and the north-east Atlantic from Mauritania to southern France.
Patella ulyssiponensis, common name the rough limpet, or China limpet is a species of sea snail, a true limpet, a marine gastropod mollusk in the family Patellidae, one of the families of true limpets. Despite its common name, the China limpet is found throughout the Eastern North Atlantic and the Mediterranean.
Patelloida heroldi is a species of sea snail, a true limpet, a marine gastropod mollusk in the family Lottiidae, one of the families of true limpets.
Scutellastra laticostata is a species of sea snail, a true limpet, a marine gastropod mollusk in the family Patellidae, one of the families of true limpets.
Tectura virginea is a species of sea snail, a true limpet, a marine gastropod mollusk in the family Lottiidae, one of the families of true limpets. It is commonly known as the white tortoiseshell limpet.
