Cerion uva (Linnaeus 1758)

Cerion uva is a species of air-breathing tropical land snail, a terrestrial pulmonate gastropod mollusk in the family Cerionidae, the peanut snails.^[1]

Description

Shells of Cerion uva can reach a length of 24 mm.^[2] This species shows extensive, geographical variations in whorl size.^[3] The shape of the shell of this species changes very much as they grow. In adults, the shells are beehive-shaped, and have an expanded labrum.^[2][4][5]

Distribution

This species is endemic to the islands of Aruba, Curaçao and Bonaire; many populations are quite different in terms of morphology and represent diverse makeup of infraspecific taxa.^[6]
