Domunculifex Littorinella
''Domunculifex littorinella'' is a species of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Geomitridae.MolluscaBase eds. (2022). MolluscaBase.

Geomitridae
Geomitridae is a taxonomic family of small to medium-sized air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Helicoidea.MolluscaBase eds. (2021). MolluscaBase. Geomitridae C.R. Boettger, 1909. Accessed through: World Register of Marine Species at: http://www.marinespecies.org/aphia.php?p=taxdetails&id=994707 on 2021-02-01 Anatomy The family is characterized by the presence of a free right ommatophoral retractor (passing outside the peni-oviducal angle) and a double stimulatory apparatus. A free right ommatophoral retractor has been linked to adaptation to xeric habitats Taxonomy The family Geomitridae is subdivided in the following subfamilies (according to Razkin ''et al.'', 2015) *Subfamily Geomitrinae ** tribe Cochlicellini Schileyko, 1972 ** tribe Geomitrini C. Boettger, 1909 - synonym: Ochthephilinae Zilch, 1960 (n.a.) ** tribe Ponentinini Razkin ''et al.'', 2015 *Subfamily Helicellinae ** tribe Cernuellini Schileyko, 1991 ** tribe ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...

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 microha ...
