Oleacinidae is a taxonomic family of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the clade Eupulmonata (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).
In this family, the number of haploid chromosomes lies between 26 and 30 (according to the values in this table). [2]
The family Oleacinidae is classified within the informal group Sigmurethra, itself belonging to the clade Stylommatophora within the clade Eupulmonata (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005). [3]
The family Oleacinidae consists of the following subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005):
Thompson (2010) [6] have redefined subfamilies in Spiraxidae and have moved Euglandininae and Streptostylinae as subfamilies of Spiraxidae.
Genera in the family Oleacinidae include:
subfamily Oleacininae
subfamily Varicellinae
Pulmonata or pulmonates, is an informal group of snails and slugs characterized by the ability to breathe air, by virtue of having a pallial lung instead of a gill, or gills. The group includes many land and freshwater families, and several marine families.
Stylommatophora is an order of air-breathing land snails and slugs, terrestrial pulmonate gastropod molluscs. This taxon includes most land snails and slugs. Stylommatophorans lack an operculum, but some close their shell apertures with temporary "operculum" (epiphragm) made of calcified mucus. They have two pairs of retractile tentacles, the upper pair of which bears eyes on the tentacle tips. All stylommatophorans are hermaphrodites.
Helicinidae is a family of small tropical land snails which have an operculum. They are terrestrial operculate gastropod mollusks in the superfamily Helicinoidea.
Planorbidae, common name the ramshorn snails or ram's horn snails, is a family of air-breathing freshwater snails, aquatic pulmonate gastropod molluscs. Unlike most molluscs, the blood of ram's horn snails contains iron-based hemoglobin instead of copper-based hemocyanin. As a result, planorbids are able to breathe oxygen more efficiently than other molluscs. The presence of hemoglobin gives the body a reddish colour. This is especially apparent in albino animals.
Chilodontaidae is a taxonomic family of mostly small deepwater sea snails, marine gastropod molluscs in the clade Vetigastropoda.
Pupillidae is a family of mostly minute, air-breathing, land snails, terrestrial pulmonate gastropod mollusks or micromollusks in the superfamily Pupilloidea.
Streptaxidae is a family of carnivorous air-breathing land snails, terrestrial pulmonate gastropod mollusks in the clade Stylommatophora. Six Streptaxidae subfamilies are accepted in the 2005 taxonomy of the Gastropoda by Bouchet & Rocroi.
Camaenidae is a family of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Helicoidea, the typical snails and their allies. This is one of the most diverse families in the clade Stylommatophora.
Euconulidae is a taxonomic family of minute, air-breathing land snails, terrestrial pulmonate gastropod mollusks or micromollusks in the superfamily Trochomorphoidea.
Euglandina is a genus of predatory medium- to large-sized, air-breathing, land snails, terrestrial pulmonate gastropod mollusks in the family Spiraxidae.
Ellobiidae, common name the hollow-shelled snails, is a family of small air-breathing land snails, terrestrial pulmonate gastropod mollusks in the clade Eupulmonata. Ellobiidae is the only family in the superfamily Ellobioidea, according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).
Xanthonychidae is a family of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Helicoidea.
Elonidae is a family of air-breathing land snails, terrestrial pulmonate gastropods mollusks in the superfamily Helicoidea.
Cepolidae is a family of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Helicoidea.
Trochomorphidae is a family of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Gastrodontoidea. Since 2017, its classification has been revised and it now belongs to the superfamily Trochomorphoidea
Spiraxidae is a family of predatory air-breathing land snails, terrestrial pulmonate gastropods in the superfamily Testacelloidea.
Aillyidae is a family of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the informal group Sigmurethra.
Urocoptidae is a family of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Urocoptoidea.
Cerionidae is a family of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Urocoptoidea.
Orthurethra is a clade of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the clade Stylommatophora.
