Lepetodrilidae
Lepetodrilidae is a family of small, deep-sea sea snails, hydrothermal vent limpets, marine gastropod molluscs in the clade Vetigastropoda (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).Bouchet, P.; Gofas, S. (2012). Lepetodrilidae. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=180906 on 2013-02-16 This family has no subfamilies. Description These deep-sea species are found and are endemic at hydrothermal vents. Their limpet-shaped shell consist of non-nacreous aragonite. The thick periostracum covers the shell edge. The apex is posterior, in some species projecting posteriorly, and deflected to the right. The shell has no sculpture or it consists of beads or imbricate radial ribs. There is no operculum. The muscle scar forms the shape of a horseshoe. The rhipidoglossate radula is special as the lateral teeth descend toward the rachidian in a v-arrangement. The conspicuous penis ...

Taxonomy Of The Gastropoda (Bouchet & Rocroi, 2005)
The taxonomy of the Gastropoda as it was revised in 2005 by Philippe Bouchet and Jean-Pierre Rocroi is a system for the scientific classification of gastropod mollusks (Gastropods are a taxonomic class of animals which consists of snails and slugs of every kind, from the land, from freshwater, and from saltwater). The paper setting out this taxonomy was published in the journal '' Malacologia''. The system encompasses both living and extinct groups, as well as some fossils whose classification as gastropods is uncertain. The Bouchet & Rocroi system was the first complete gastropod taxonomy that primarily employed the concept of clades, and was derived from research on molecular phylogenetics; in this context a clade is a "natural grouping" of organisms based upon a statistical cluster analysis. In contrast, most of the previous overall taxonomic schemes for gastropods relied on morphological features to classify these animals, and used taxon ranks such as order, superorder ...

Limpet
Limpets are a group of aquatic snails with a conical gastropod shell, 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 Brain, cerebral, foot, pedal, and pleural sets of ganglion, ganglia. These ganglia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sculpture (mollusc)
Sculpture is a feature of many of the shells of mollusks. It is three-dimensional ornamentation on the outer surface of the shell, as distinct from either the basic shape of the shell itself or the pattern of colouration, if any. Sculpture is a feature found in the shells of gastropods, bivalves, and scaphopods. The word "sculpture" is also applied to surface features of the aptychus of ammonites, and to the outer surface of some calcareous opercula of marine gastropods such as some species in the family Trochidae. Sculpture can be concave or convex, incised into the surface or raised from it. Sometimes the sculpture has microscopic detailing. The term "sculpture" refers only to the calcareous outer layer of shell, and does not include the proteinaceous periostracum, which is in some cases textured even when the underlying shell surface is smooth. In many taxa, there is no sculpture on the shell surface at all, apart from the presence of fine growth lines. The sculp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gigantopelta Chessoia
''Gigantopelta chessoia'' is a species of deep sea snail from hydrothermal vents, a marine gastropod mollusk in the family Peltospiridae. Taxonomy The first information about this species, under the name "Peltospiroidea n. sp." or "peltospiroid gastropod", was published on 3 January 2012. Peltospiroidea is the name of a superfamily of gastropods that was used in the taxonomy of the Gastropoda (Ponder & Lindberg, 1997). It contained only the extant family Peltospiridae and some prehistoric gastropod families. However, the taxonomy of the Gastropoda (Bouchet & Rocroi, 2005) does not use the name Peltospiroidea (in that system, Peltospiridae is placed within the superfamily Neomphaloidea). It was described as a new species within the new genus ''Gigantopelta'' in 2015, in the family Peltospiridae. Distribution This species is known from two sites near hydrothermal vents in the East Scotia Ridge of the south Atlantic Ocean: from 2,394 m depth at the E9 vent site and from the ...

Scotia Sea
The Scotia Sea is a sea located at the northern edge of the Southern Ocean at its boundary with the South Atlantic Ocean. It is bounded on the west by the Drake Passage and on the north, east, and south by the Scotia Arc, an undersea ridge and island arc system supporting various islands. The sea sits atop the Scotia Plate. It is named after the expedition ship Scotia (barque), ''Scotia''. Many icebergs melt there. Location and description The Scotia Sea is the area of water between the Drake Passage, Tierra del Fuego, South Georgia Island, South Georgia, the South Sandwich Islands, the South Orkney Islands, and the Antarctic Peninsula. These island groups all sit atop the Scotia Arc, which frames the sea on the north, east, and south. The Scotia Sea covers an area around . About half of the sea stands above the continental shelf. History The sea was named about 1932 after the ''Scotia (barque), Scotia'', the expedition ship used in these waters by the Scottish National Antarcti ...

James Hamilton McLean
James Hamilton McLean (17 June 1936 – 11 November 2016) was an American malacologist (a biologist who studies mollusks). He specialized in marine gastropods. He worked on many families of Eastern Pacific gastropods including the Fissurellidae, Trochidae, Turbinidae and Liotiidae, and also investigated deep sea gastropods from hydrothermal vents. McLean worked as a curator of the Natural History Museum of Los Angeles County from 1964 to 2001 and was a curator emeritus there until his death in November 2016. Molluscs described McLean, often together with other malacologists, described, according to the database WoRMS, 385 new taxa.(7 December 2007) from Natural History Museum of Los Angeles County website At least 37 taxa were named for James McLean with the epithet ''macleani'' (according to WoRMS) He named numerous taxa of marine gastropods including: * Clypeosectidae McLean, 1989, a family of hydrothermal vent limpets Bibliography * Handbook, 1969, revised in 1978, ' ...
