Helicidae
Helicidae is a large, diverse family of western Palaearctic, medium to large-sized, air-breathing land snails, sometimes called the "typical snails." It includes some of the largest European land snails, several species are common in anthropogenic habitats, and some became invasive on other continents. A number of species in this family are valued as food items, including '' Cornu aspersum'' (formerly ''Helix aspersa;'' "petit gris") the brown or garden snail, and '' Helix pomatia'' (the " escargot"). The biologies of these two species in particular have been thoroughly studied and documented. Shell description The shells are usually flattened or depressed conical. Globular shells are found in the genera '' Helix'', '' Maltzanella'', '' Lindholmia'', '' Cornu'', '' Cantareus'', '' Eremina'', and '' Idiomella''. One species, '' Cylindrus obtusus'', has a cylindrical shell. In some genera, especially in '' Cepaea'', the shells are brightly colored and patterned. Anatomy Hel ...

Helix (gastropod)
''Helix'' is a genus of large, air-breathing land snails native to the western Palaearctic and characterized by a globular shell. It is the type genus of the family Helicidae, and one of the animal genera described by Carl Linnaeus at the dawn of the zoological nomenclature. Members of the genus first appeared in the fossil record during the Miocene. Well-known species include '' Helix pomatia'' (Roman snail, Burgundy snail, or edible snail) and '' Helix lucorum'' (Turkish snail). ''Cornu aspersum'' (garden snail), though externally similar and long classified as a member of ''Helix'' (as "''Helix aspersa''"), is not closely related to ''Helix'' and belongs to a different tribe of Helicinae. Taxonomy In Linnaeus' 10th edition of Systema Naturae, which marks the beginning of the zoological nomenclature, the generic name ''Helix'' had been used for a variety of terrestrial (e.g. '' Zonites algirus''), freshwater (e.g. ''Lymnaea stagnalis''), and marine (e.g. '' Fossarus amb ...

Cornu Aspersum
''Cornu aspersum'' (syn. ''Helix aspersa'', ''Cryptomphalus aspersus''), known by the common name garden snail, is a species of land snail in the family Helicidae, which includes some of the most familiar land snails. Of all terrestrial molluscs, this species may well be the most widely known. It was classified under the name ''Helix aspersa'' for over two centuries, but the prevailing classification now places it in the genus ''Cornu''. The Garden Snail is relished as a food item in some areas, but it is also widely regarded as a pest in gardens and in agriculture, especially in regions where it has been introduced accidentally, and where snails are not usually considered to be a menu item. Description The adult bears a hard, thin calcium carbonate, calcareous shell in diameter and high, with four or five Whorl (mollusc), whorls. The shell is variable in coloring and shade of color, but generally it has a reticulated pattern of dark brown, brownish-golden, or chestnut with ...

White-lipped Snail
The white-lipped snail or garden banded snail, scientific name ''Cepaea hortensis'', is a large species of air-breathing land snail, a terrestrial pulmonate gastropod mollusc in the family Helicidae. The only other species in the genus is ''Cepaea nemoralis''. Shell description ''Cepaea hortensis'' has a shell up to in diameter, tending to be slightly smaller than ''C. nemoralis''. The umbilicus is closed in adults, but narrowly open in juveniles. Although the shells of ''C. hortensis'' are most commonly yellow, they exhibit a range of background colours from brown through pink to pale yellow, and up to five brown bands may be present, some of which may fuse with their neighbours. This polymorphism, which is shared with ''Cepaea nemoralis'', has been the subject of considerable research. Identification In most areas adults of ''C. hortensis'' can be distinguished by the pale colouration of the lip around the shell aperture, whereas it is typically brown in ''C. nemoral ...

Helicinae
Helicinae is a subfamily of terrestrial gastropods in the family Helicidae. It contains mostly large land snail species, distributed in the western Palaearctic. The most recent (as of 2023) classification proposed division into three tribes. The subfamily contains the largest helicids, and includes widely known, widespread species like the garden snail ''Cornu aspersum'' (syn.

Cepaea
''Cepaea'' is a genus of large air-breathing land snails, terrestrial molluscs, terrestrial pulmonate gastropod molluscs in the family Helicidae. The shells are often brightly coloured and patterned with brown stripes. The two living species in this genus, ''C. nemoralis'' and ''C. hortensis'', are widespread and common in Western and Central Europe. In North America, ''C. hortensis'' is Native species, native on the northeast coast, but both species have been introduced elsewhere, and they are also spreading further east in Europe. Both have been influential model organisms, model species for ongoing studies of genetics and natural selection. Like many Helicidae, these snails use love darts during mating. Species For a long time, four living species were classified in the genus ''Cepaea''. However, Molecular phylogenetics, molecular phylogenetic studies suggested that two of them should be placed in the genera ''Macularia'' and ''Caucasotachea'', which are not immediate relativ ...

Land Snail
A land snail is any of the numerous species of snail that live on land, as opposed to the sea snails and freshwater snails. ''Land snail'' is the common name for terrestrial molluscs, terrestrial gastropod mollusks that have gastropod shell, shells (those without shells are known as slugs). However, it is not always easy to say which species are terrestrial, because some are more or less amphibious between land and fresh water, and others are relatively amphibious between land and salt water. Land snails are a Polyphyly, polyphyletic group comprising at least ten independent evolutionary transitions to terrestrial life (the last common ancestor of all gastropods was marine). The majority of land snails are pulmonates that have a lung and breathe air. Most of the non-pulmonate land snails belong to lineages in the Caenogastropoda, and tend to have a gill and an operculum (gastropod), operculum. The largest clade of non-pulmonate land snails is the Cyclophoroidea, with more than 7,0 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helix Pomatia
''Helix pomatia'', known as the Roman snail, Burgundy snail, or escargot, is a species of large, air-breathing stylommatophoran land Snails, snail native to Europe. It is characterized by a globular brown shell. It is an edible species which commonly occurs Synanthrope, synanthropically throughout its range. Distribution The present Species distribution, distribution of ''Helix pomatia'' is considerably affected by the dispersion by human and synanthropic occurrences. The northern limits of their natural distribution run presumably through central Germany and southern Poland with the eastern range limits running through western-most Ukraine and Moldova/Romania to Bulgaria. In the south, the species reaches northern Bulgaria, central Serbia, Bosnia and Herzegovina, Bosnia and Hezegovina and Croatia. It occurs in northern Italy southwards to the Po (river), Po and the Ligurian Apennines. Westerly the native range extends to eastern France. Currently, ''H. pomatia'' is distribut ...
