Patellidae
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 Synonyms Synonyms include the following: * ''Ansates'' G.B.

Scutellastra Mexicana
''Scutellastra mexicana'' is a species of true limpet, a marine gastropod mollusk in the family Patellidae. It is the largest known limpet in the world. This species has been harvested since pre-Hispanic times. In Mexico, it was harvested heavily in the 1970s and 1980s, leading to closing of the fishery in 1988. However, the harvest has continued, and it is feared that ''Scutellastra mexicana'' is in danger of extinction. Description ''Scutellastra mexicana'' can reach in length. Distribution and habitat ''Scutellastra mexicana'' occurs along the American Pacific coast from Mexico to Peru. It inhabits lower intertidal The intertidal zone or foreshore is the area above water level at low tide and underwater at high tide; in other words, it is the part of the littoral zone within the tidal range. This area can include several types of habitats with various sp ... and subtidal rocky areas exposed to heavy swells. References Further reading * Patellidae Molluscs o ...

Patella (gastropod)
''Patella'' are a herbivorous ''genus'' of sea snails limpets in the family ''Patellidae'', further placed under the class ''Gastropoda''. Primarily a marine based genus of prosobranch gastropods they most commonly live on coastal tidal shores in varying non tropical climates. As limpets under family Patellidae, they share sister taxa with 3 other accepted genus Cymbula, Helcion, and x ..., and Scutellastra. ''Patella'' is characterized by their cup-shaped shell and gills, with their form of movement in waves. The genus of ''Patella'' are geographically found around north eastern Atlantic and Mediterranean tidal beds. Surveys conducted over the 4 genus' habitat distribution show that ''Patella'' are generally the northern most genus with the other 3 distributing along south eastern Africa towards Asia. They tend to be subjected to high volumes of environmental stresses and therefore act as key indicator species for the tidal coast health in those regions. As such conservation ef ...

Patella Vulgata
''Patella vulgata'', common name the common limpet or common European limpet is a species of sea snail. It is a typical true limpet; a marine gastropod mollusc in the family Patellidae, with gills.Gofas, S. (2014). Patella vulgata Linnaeus, 1758. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=140685 on 2014-10-29 This species occurs in the waters of Western Europe. Radula The radula in this species is longer than the shell itself. It contains 1,920 teeth in 160 rows of 12 teeth each. ''Patella vulgata'' is found attached to firm substrates from the high shore to the edge of the sublittoral zone, although it predominates in areas of wave action. Its shell is conical, up to around 6 cm long, and lacks defined chirality. Common limpets are believed to be able to live for up to twenty years. ''Patella vulgata'' has been the focus of a range of scientific investigation, as far back as 1935. Its development is well de ...

Patellogastropoda
The Patellogastropoda, common name true limpets and historically called the Docoglossa, are members of a major phylogenetic group of marine (ocean), marine gastropods, treated by experts either as a clade or as a taxonomic Order (biology), order. The clade Patellogastropoda is deemed monophyletic based on phylogenetic analysis. Taxonomy Patellogastropoda was proposed by David R. Lindberg, 1986, as an order, and was later included in the subclass Eogastropoda Ponder & Lindberg, 1996. 2005 taxonomy Taxonomy of the Gastropoda (Bouchet & Rocroi, 2005), Bouchet & Rocroi, 2005 designated Patellogastropoda, true limpets, as a clade, rather than as a taxon, but within included superfamilies and families as listed below.

Limpets
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 (its members descending from different immediate ancestors). All species of Patellogastropoda are limpets, with the Patellidae family in particular often referred to as "true limpets". Examples of other clades commonly referred to as limpets include the Vetigastropoda family Fissurellidae ("keyhole limpet"), which use a siphon to pump water over their gills, and the Siphonariidae ("false limpets"), which have a pneumostome for breathing air like the majority of terrestrial Gastropoda. Description The basic anatomy of a limpet consists of the usual molluscan organs and systems: * A nervous system centered around the paired cerebral, pedal, and pleural sets of ganglia. These ganglia create a ring around the limpet's eso ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
