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 gastropod mollusks that have 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 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. The largest clade of land snails is the Cyclophoroidea, with more than 7,000 species. Many of these operculate land snails live in habitats or microhabitats ...

Terrestrial Molluscs
Terrestrial molluscs or land molluscs (mollusks) are an ecological group that includes all molluscs that live on land in contrast to freshwater and marine molluscs. They probably first occurred in the Carboniferous, arising from freshwater ones. Characteristics This group includes land snails and land slugs. Loss of the shell has taken place many times in different groups that are not evolutionarily closely related, and land snails and slugs are most often treated together as a single group in specialized malacological literature.Barker G. M. (ed.) The biology of terrestrial molluscs'. CABI Publishing, 2001, 558 pp. .Barker G. M. (ed.) Natural enemies of terrestrial molluscs'. CABI Publishing, 2004, 644 pp. . All terrestrial molluscs belong to the class Gastropoda. However, colonization of the land took place several times during the evolutionary past, and as a result terrestrial molluscs are classified in several different, often not closely related, gastropod taxa.

Grove Snail
The grove snail, brown-lipped snail or Lemon snail (''Cepaea nemoralis'') is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusc. MolluscaBase eds. (2020). MolluscaBase. Cepaea nemoralis (Linnaeus, 1758). Accessed through: World Register of Marine Species at: http://marinespecies.org/aphia.php?p=taxdetails&id=235792 on 2020-07-31 It is one of the most common species of land snail in Europe, and has been introduced to North America. ;Subspecies: * ''Cepaea nemoralis etrusca'' (Rossmässler, 1835) * ''Cepaea nemoralis nemoralis'' (Linnaeus, 1758) ''Cepaea nemoralis'' is the type species of the genus ''Cepaea''. It is used as a model organism in citizen science projects. Description ''Cepaea nemoralis'' is among the largest and, because of its polymorphism and bright colours, one of the best-known snails in Western Europe. The colour of the shell of ''Cepaea nemoralis'' is very variable; it can be reddish, brownish, yellow or whitish, with or with ...

Cepaea
''Cepaea'' is a genus of medium-sized air-breathing land snails, terrestrial molluscs, terrestrial pulmonate gastropod mollusks in the family Helicidae. The shells of species within this genus are often brightly colored and patterned with stripes. The two species from this genus, the common and widespread ''C. nemoralis'' and ''C. hortensis'', have been model species for early studies of genetics and natural selection. They occur in Europe, although introduced populations occur elsewhere in the world. Like many Helicidae, this genus of snails create and use love darts. Species For a long time, four species were classified in the genus ''Cepaea''. However, Molecular phylogenetics, molecular phylogenetic studies suggested that the latter two should be placed in the unrelated genera ''Macularia'' and ''Caucasotachea'': * ''White-lipped snail, Cepaea hortensis'' (O. F. Müller, 1774) – white-lipped snail or garden banded snail * ''Grove snail, Cepaea nemoralis'' (Linnaeus, 1758) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helicidae
Helicidae is a large, diverse family of small to large, air-breathing land snails, sometimes called the "typical snails." A number of species in this family are valued as food items, including ''Cornu aspersum'' (formerly ''Helix aspersa'') 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 of these snails are mostly rather globular in shape. In some genera, such as ''Cepaea'', the shells are brightly colored and patterned. Anatomy The animal is capable of complete retraction within the shell. The tail is without a mucous gland or projection. Tryon G. W. 1887 ''Manual of conchology; structural and systematic. With illustrations of the species''. Second series: PulmonataVolume 3 Helicidae - Volume I. pag3€“4. The mouth is always provided with a jaw, which is striate, ribbed, sulcate or plicate, sometimes composed of several imbricating piece ...
