Madeiran Land Snail

Atlantica gueriniana

Unknown

Overview

Atlantica gueriniana is a species of small air-breathing land snail, a terrestrial gastropod mollusk presently in the family Gastrodontidae, but formerly in Discidae, the disk snails.

The Madeiran Land Snail faces severe threats from habitat destruction and degradation on the island of Madeira, where its native laurel forest ecosystem has been extensively cleared for agriculture and development. Introduced species, particularly invasive plants and predatory species, have further compromised the remaining suitable habitat. Climate change and increased frequency of droughts pose additional stress to this moisture-dependent species.
