Partulidae is a family of air-breathing land snails, terrestrial gastropod mollusks in the superfamily Partuloidea. The family is endemic to Pacific islands.[1][2][3]

GeneraEdit

The Partulidae are divided into five genera: [3][4]

This cladogram shows the phylogenic relationships of genera in the family Partulidae:[3][5]


Partulidae

Partula

Samoana

Palaopartula

Eua

Sphendone

AnatomyEdit

In this family, the number of haploid chromosomes lies between 26 and 30 (according to the values in this table).[6]

SignificanceEdit

The Partulidae represent a significant species radiation and were important in the development of modern evolutionary studies through the work of Henry Crampton in the early 20th century and later by Bryan Clarke, James Murray and Michael Johnson.

StatusEdit

Most Partulidae species have declined since 1974 and a very large proportion are extinct. The main threat to their survival has been the introduction of the predatory snail Euglandina rosea.[3]
