Escargot De Quimper
''Elona quimperiana'', common name the escargot de Quimper ("Quimper snail"), is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Elonidae. ''Elona'' is a monotypic genus, i.e. it contains only one species, ''Elona quimperiana''. The specific name comes from the city of Quimper in Brittany, France. This snail is mentioned in annexes II and IV of the Habitats Directive. Original description ''Elona quimperiana'' was originally described (under the name ''Helix quimperiana'') by André Étienne d'Audebert de Férussac in 1821. Férussac's original text (the type description) reads in the French language as follows: Which means in English: "Habitat: Margin of Briec (Briec-de-l'Odet) near Quimper in Brittany. It was found by Messieurs De Kermovan and Bonnemaison." Shell description The shell is umbilicate and planorboid in shape. The spire is slightly concave. The periphery is broadly rounded, corneous with a few varicoid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Brittany (administrative Region)
The region Brittany ( ; ; Gallo: ''Bertaèyn'' ) is an administrative region of Metropolitan France, comprising the departments of Côtes-d'Armor, Finistère, Ille-et-Vilaine, and Morbihan. Its capital and largest city is Rennes. Bordered by the English Channel to the north, the Celtic Sea to the west, and the Atlantic Ocean ( Bay of Biscay) to the south, Brittany's neighboring regions are Normandy to the northeast and Pays de la Loire to the southeast. It is one of two regions in Metropolitan France where all departments have direct access to the sea, the other being Corsica. The region of Brittany is sometimes referred to as “administrative Brittany” in contrast to “historical Brittany” or “cultural Brittany”, which also includes the Loire-Atlantique and the question of its connection with the rest of the administrative region is being discussed. History Brittany, located in the west-northwest corner of France, is one of the historic province ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Disjunct Distribution
In biology, a taxon with a disjunct distribution is one that has two or more groups that are related but considerably separated from each other geographically. The causes are varied and might demonstrate either the expansion or contraction of a species' range. Range fragmentation Also called range fragmentation, disjunct distributions may be caused by changes in the environment, such as mountain building and continental drift or rising sea levels; it may also be due to an organism expanding its range into new areas, by such means as rafting, or other animals transporting an organism to a new location (plant seeds consumed by birds and animals can be moved to new locations during bird or animal migrations, and those seeds can be deposited in new locations in fecal matter). Other conditions that can produce disjunct distributions include: flooding, or changes in wind, stream, and current flows, plus others such as anthropogenic introduction of alien introduced species either accid ...

Love Dart
A love dart (also known as a gypsobelum, shooting darts, or just as darts) is a sharp, calcium carbonate, calcareous or chitinous Dart (missile), dart which some hermaphroditic land snails and slugs create. Love darts are both formed and stored internally in a dart sac. These darts are made in sexually mature animals only, and are used as part of the sequence of events during courtship display, courtship, before actual mating takes place. Darts are quite large compared to the size of the animal: in the case of the semi-slug genus ''Parmarion'', the length of a dart can be up to one fifth that of the semi-slug's foot. The process of using love darts in snails is a form of sexual selection. Prior to copulation (zoology), copulation, each of the two snails (or slugs) attempts to "shoot" one (or more) darts into the other snail (or slug). There is no organ to receive the dart; this action is more analogous to stabbing, or to being shot with an arrow or flechette. The dart does not ...

Helicoidea
Helicoidea is a Taxonomy (biology), taxonomic Taxonomic rank, superfamily of air-breathing land snails, terrestrial molluscs, terrestrial pulmonate gastropod mollusks in the order (taxonomy), order Stylommatophora. Taxonomy 2017 taxonomy and latest developments The Bouchet et al. 2017 nomenclator provides an up to date system of Helicoidea. The system is in some parts preliminary, as the authors relied on unpublished (as of 2023) Phylogenomics, phylogenomic study, which did not include all New World taxa. They classified Epiphragmophoridae, Helminthoglyptidae, Humboldtianidae, Monadeniidae and Xanthonychidae (provisionally also Lysinoidae and Echinichidae) as Subfamily, subfamilies of the last taxon, because there are no deep splits between them in the cited unpublished study (see also Koene & Schulenburg 2005). Cepolidae, Labyrinthidae and Thysanophoridae constitute the sister group of the remaining Helicoidea. * Camaenidae Pilsbry, 1895 * Canariellidae Schileyko, 1991 * Cepo ...

Reproductive System Of Gastropods
The reproductive system of gastropods (slugs and snails) varies greatly from one group to another within this very large and diverse taxonomic class of animals. Their reproduction, reproductive strategies also vary greatly. In many marine (ocean), marine gastropods, there are separate sexes (male and female); most Terrestrial animal, terrestrial gastropods however are hermaphrodites. Courtship display, Courtship is a part of the behaviour of mating of gastropods, mating gastropods. In some families of pulmonate land snails, one unusual feature of the reproductive system and reproductive behavior is the creation and utilization of love darts, the throwing of which has been identified as a form of sexual selection. Gastropods reproductive systems vary significantly from one taxonomic group to another. They can be separated into three categories: Marine (ocean), marine, Fresh water, freshwater, and land.

Alfred Moquin-Tandon
Christian Horace Benedict Alfred Moquin-Tandon (7 May 1804 – 15 April 1863) was a French Natural history, naturalist and doctor. Moquin-Tandon was professor of zoology at Marseille from 1829 until 1833, when he was appointed professor of botany and director of the botanical gardens at Toulouse. In 1850, he was sent by the French government to Corsica to study the island's flora. In 1853, he moved to Paris, later becoming director of the Jardin des Plantes and the Académie des Sciences. His books included the ornithology section of ''L'Histoire Naturelle des Iles Canaries'' (1835–44), co-authored with Philip Barker Webb and Sabin Berthelot. One of his specialities was the Family (biology), family Amaranthaceae (The Amaranth family). Several genera of plants have been named in his honour, including in 1838, DC. published ''Moquinia'', a genus of flowering plants from Brazil, in the Moquinieae, ''Moquinia'' tribe within the Asteraceae, sunflower family.

Aperture (mollusc)
The aperture is an opening in certain kinds of mollusc shells: it is the main opening of the shell, where the head-foot part of the body of the animal emerges for locomotion, feeding, etc. The term ''aperture'' is used for the main opening in gastropod shells, scaphopod shells, and also for ''Nautilus'' and ammonite shells. The word is not used to describe bivalve shells, where a natural opening between the two shell valves in the closed position is usually called a ''gape (bivalve), gape''. Scaphopod shells are tubular, and thus they have two openings: a main anterior aperture and a smaller posterior aperture. As well as the aperture, some gastropod shells have additional openings in their shells for respiration; this is the case in some Fissurellidae (keyhole limpets) where the central smaller opening at the apex (mollusc), apex of the shell is called an orifice, and in the Haliotidae (abalone) where the row of respiratory openings in the shell are also called orifices.

Whorl (mollusc)
A whorl is a single, complete 360° revolution or turn in the spiral or whorled growth of a mollusc shell. A spiral configuration of the shell is found in numerous gastropods, but it is also found in shelled cephalopods including ''Nautilus'', ''Spirula'' and the large extinct subclass of cephalopods known as the ammonites. A spiral shell can be visualized as consisting of a long Cone (geometry), conical tube, the growth of which is coiled into an overall Helix, helical or planispiral shape, for reasons of both strength and compactness. The number of whorls which exist in an adult shell of a particular species depends on mathematical factors in the geometric growth, as described in D'Arcy Wentworth Thompson's classic 1917 book ''On Growth and Form'', and by David Raup. The main factor is how rapidly the conical tube expands (or flares-out) over time. When the rate of expansion is low, such that each subsequent whorl is not that much wider than the previous one, then the adult s ...
