Overview

Trochoidea cucullus is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Geomitridae, the hairy snails and their allies.SubspeciesTrochoidea cucullus cucullus (E. von Martens, 1875) Trochoidea cucullus despotti (Soós, 1933) Trochoidea cucullus soosi Beckmann, 2003

Trochoidea cucullus faces severe population decline due to habitat destruction from urban development and agricultural expansion across its limited Mediterranean range. The species' restricted distribution makes it particularly vulnerable to localized threats, with remaining populations fragmented and isolated. Overgrazing by livestock has degraded the specific microhabitat conditions this terrestrial gastropod requires for survival.

Threat summary

Habitat

This terrestrial snail inhabits dry Mediterranean scrubland and rocky limestone areas with sparse vegetation. It requires specific microhabitat conditions including adequate moisture retention and shelter among rocks and low shrubs.
