Ellobiidae, common name the hollow-shelled snails, is a family of small air-breathing land snails, terrestrial pulmonate gastropod mollusks in the clade Eupulmonata. [2] Ellobiidae is the only family in the superfamily Ellobioidea, according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005). [3]
In this family, the number of haploid chromosomes lies between 16 and 20 (according to the values in this table). [4]
They have a distinctive mode of locomotion arising due to a split sole. The front part of the sole adheres to the substrate and then the rear part of the sole is drawn up to the front part. [5]
Species are traditionally classified into five taxonomic groups, the Pythiidae, the Laemodontidae, the Melampodidae, the Ellobiidae and the Carychiidae. [1] These taxa have been recognized either as families within Ellobioidea or as sub-families within the family Ellobiidae. [1]
The family Ellobiidae consists of the following subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005): [3]
The high degree of homoplasy in morphological characters and frequent low variability has led to the description of approximately 800 species names available in the literature, of which 250 are likely to be valid. [1]
A molecular study by Dayrat at al. (2011) [6] for the Ellobioidea suggests a monophyletic origin of the entire group. [1]
Genera within the family Ellobiidae include:
subfamily Ellobiinae
subfamily Carychiinae
subfamily Melampinae
subfamily Pedipedinae
subfamily Pythiinae Odhner, 1925
† subfamily Zaptychiinae

Genus Sarnia H. Adams & A. Adams, 1855 (temporary name, Sarnia [H. & A. Adams, 1855 (September), The Genera of Recent Mollusca, 2: 239] is an incorrect subsequent spelling of Siona H. Adams & A. Adams, 1855 which is a junior homonym of Siona Duponchel, 1829 [Lepidoptera].)
The taxon Ellobioidea comprises a group of morphologically and ecologically highly diverse snails, known to have successfully invaded the marine, brackish water and terrestrial habitats. [1]
These are mostly snails that live in salt marshes and similar maritime habitats, and thus have a tolerance for saline conditions.
Ocenebrinae is a taxonomic subfamily of predatory sea snails, marine gastropod mollusks. This subfamily is within the large family Muricidae, which are commonly known as the murex and rock snails.
Pyramidellidae, common name the pyram family, or pyramid shells, is a voluminous taxonomic family of mostly small and minute ectoparasitic sea snails, marine heterobranch gastropod molluscs. The great majority of species of pyrams are micromolluscs.
Tiberia is a genus of minute parasitic sea snails, marine gastropod molluscs in the family Pyramidellidae, the pyrams and their allies. Tiberia is the only genus in the tribe Tiberiini.
Olive snails, also known as olive shells and olives, scientific name Olividae, are a taxonomic family of medium to large predatory sea snails with smooth, shiny, elongated oval-shaped shells.
Turbinidae, the turban snails, are a family of small to large marine gastropod molluscs in the superfamily Trochoidea.
The Buccinidae are a very large and diverse taxonomic family of large sea snails, often known as whelks or true whelks.
Basommatophora was a term that was previously used as a taxonomic informal group, a group of snails within the informal group Pulmonata, the air-breathing slugs and snails. According to the taxonomy of the Gastropoda, whenever monophyly has not been tested, or where a traditional taxon of gastropods has now been discovered to be paraphyletic or polyphyletic, the term "group" or "informal group" was used.
Calliostomatidae is a family of sea snails within the superfamily Trochoidea and the clade Vetigastropoda.
Eupulmonata is a taxonomic clade of air-breathing snails. The great majority of this group are land snails and slugs, but some are intertidal or inhabit coastal saltmarshes and mangroves.
Mitridae, known as mitre shells, are a taxonomic family of sea snails, widely distributed marine gastropod molluscs in the clade Mitroidea.
The Nassariidae, Nassa mud snails (USA), or dog whelks (UK), are a taxonomic family of small to medium-sized sea snails, marine gastropod mollusks in the clade Neogastropoda.
Chondrinidae is a family of mostly minute air-breathing land snails, terrestrial pulmonate gastropod mollusks in the order Pulmonata.
Oleacinidae is a taxonomic family of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the clade Eupulmonata.
Myosotella is a European genus or subgenus of small, salt marsh snails, terrestrial pulmonate gastropod mollusks in the subfamily Pythiinae of the family Ellobiidae.
The Harpidae, known as the harp snails, are the members of a taxonomic family of large predatory sea snails, marine gastropod mollusks.
Coralliophilinae is a taxonomic group, a subfamily of about 200–250 sea snails, marine gastropod mollusks commonly known as the coral snails or coral shells. This is a subfamily within the very large family Muricidae, the murex or rock snails.
Marinula is a genus of small air-breathing land snails, terrestrial pulmonate gastropod molluscs in the family Ellobiidae.
Ellobium is a genus of medium-sized, air-breathing, saltmarsh snails, terrestrial pulmonate gastropod mollusks in the family Ellobiidae.
Ovatella is a genus of gastropods belonging to the family Ellobiidae.
Pedipes is a genus of small air-breathing snails, pulmonate gastropod mollusks in the subfamily Pedipedinae of the family Ellobiidae.
