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 the diverse makeup of infraspecific taxa. ^[6]
