Clausiliidae, also known by the common name door snails, is a taxonomic family of small, very elongate, mostly left-handed, air-breathing land snails, sinistral terrestrial pulmonate gastropod mollusks.[2]

With over 1700 recognized recent and fossil species,[2] this is among the most diverse families of terrestrial gastropods (cf. Orthalicidae), although the marine gastropod family Pyramidellidae is larger.

Most species of Clausiliidae have an anatomical structure known as a clausilium, which enables the snail to close off the aperture of the shell with a sliding "door".

Shell description[edit]

Megalophaedusa martensi is the largest species of the family Clausiliidae in the world. The individual in the photograph has a shell which is 45.5 mm long. The whole snail weighs 3.2 g live.

Almost all the species of snails in the family of door snails are left-handed, which is an uncommon feature in gastropod shells in general.

These snails have shells which are extremely high-spired, with numerous whorls.

The shells tend to be club-shaped, tapering at both ends to a rounded nub. The aperture usually has visible folds.

The clausilium[edit]

Main article: clausilium
The clausilium of Clausilia dubia

Clausiliids are also very unusual among pulmonate gastropods in that most of them have a "door" or clausilium. The clausilium is not the same thing as an operculum, which does not exist at all in pulmonate gastropods.

The clausilium is a calcareous structure, tongue-shaped or spoon-shaped, which can close the aperture of the snail shell to protect the soft parts against predation by animals such as carnivorous beetle larvae. The narrow end of the clausilium slides in the grooves that are formed by the folds on the inside of the shell.

Anatomy[edit]

In this family, the number of haploid chromosomes lies between 21 and 30 (according to the values in this table).[3]

Taxonomy[edit]

The type genus is Clausilia Draparnaud, 1805.

The family Clausiliidae 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).[4]

Conservation[edit]

Although non-marine molluscs appear to be exceptionally vulnerable to extinction,[16] the IUCN Red list listed only 9 species[17] from this family.
