Cerion uva

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

Description
Shells of Cerion uva can reach a length of 24 mm. This species shows extensive, geographical variations in whorl size. 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.

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.
