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.
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.
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.)
Seashore wildlife habitats exist from the Tropics to the Arctic and Antarctic. Seashores and beaches provide varied habitats in different parts of the world, and even within the same beach. Phytoplankton is at the bottom of some food chains, while zooplankton and other organisms eat phytoplankton. Kelp is also autotrophic and at the bottom of many food chains. Coastal areas are stressed through rapid changes, for example due to tides.
Cellana nigrolineata is a species of sea snails or limpets, marine gastropod molluscs in the family Nacellidae, one of the families of true limpets.
Cymbula adansonii is a species of sea snail, a true limpet, a marine gastropod mollusc in the family Patellidae. It is one of the several families of true limpets. Marine gastropods, colloquially classified as snails and slugs, encompass the entire class of invertebrates in the Mollusca phylum. True limpets, are pelagic snails within the Patellidae family.
Cymbula compressa is a species of sea snail, a true limpet, a marine gastropod mollusc in the family Patellidae, one of the families of true limpets.
Cymbula depsta is a species of sea snail, a true limpet, a marine gastropod mollusc in the family Patellidae, one of the families of true limpets.
Cymbula miniata is a species of sea snail, a true limpet, a marine gastropod mollusc in the family Patellidae, one of the families of true limpets.
Cymbula safiana, common name the saffian limpet, is a species of sea snail, a true limpet, a marine gastropod mollusc in the family Patellidae, one of the families of true limpets.
Cymbula oculus is a species of sea snail, a true limpet, a marine gastropod mollusc in the family Patellidae, one of the families of true limpets.
Helcion concolor, common name the variable 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.
Lottia digitalis, commonly known as the fingered limpet or ribbed limpet, is a species of sea snail, a true limpet, a marine gastropod mollusk in the family Lottiidae. These limpets are usually found on the surface of rocks in the high intertidal region on the coastal fringes of the north-eastern Pacific Ocean.
Lottia scabra or the rough limpet is a species of sea snail, a true limpet, a marine gastropod mollusk in the family Lottiidae.
Patella ferruginea, commonly known as the ferruginous limpet is a species of true limpet, a marine gastropod mollusk in the family Patellidae. It is a large limpet, endemic to the western Mediterranean Sea, and although common in the past, it is now rare and restricted to only a few locations.
Scutellastra argenvillei or Argenville's 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.
Scutellastra cochlear is a species of sea snail, a marine gastropod mollusc in the family Patellidae, one of the families of true limpets. It is commonly known as the snail patella, the pear limpet or the spoon limpet and is native to South Africa. It often grows in association with the crustose coralline alga Spongites yendoi and a filamentous red alga which it cultivates in a garden. It was first described by the malacologist Ignaz von Born in 1778 as Patella cochlear.
Scutellastra longicosta, the long-spined limpet or the duck's foot limpet, is a species of true limpet, a marine gastropod mollusk in the family Patellidae, one of the families of true limpets. It is native to the coasts of South Africa where it is found on the foreshore. It cultivates a species of crustose brown algae in a "garden".
Cymbula is a genus of sea snails, the true limpets, marine gastropod mollusks in the family Patellidae.
Cymbula sanguinans, the giant pinkray limpet, is a species of giant limpet, a marine mollusc in the family Patellidae. It is native to the coast of South Africa. At one time thought to be a subspecies of Cymbula miniata, molecular analysis has shown C. sanguinans warrants being treated as a full species, despite there being no obvious morphological differences between the two. This makes difficult the task of deciding which of the previous research studies refer to C. sanguinans, and which refer to C. miniata.
