Overview

Testudodiscula testudinalis a species of small land snail, a terrestrial pulmonate gastropod mollusc in the family Geomitridae.

Testudodiscula testudinalis faces severe population decline primarily due to habitat destruction from agricultural expansion and urban development across its limited range. The species' specialized ecological requirements make it particularly vulnerable to environmental changes, while its small population size increases extinction risk from stochastic events. Collection pressure for the shell trade has further reduced already fragmented populations.

Threat summary

Habitat

This terrestrial gastropod inhabits limestone karst formations and rocky outcrops with specific moisture and temperature requirements. The species is typically found in crevices and under rocks in areas with particular soil chemistry and vegetation cover.

Frequently asked questions

Why is Testudodiscula testudinalis classified as Critically Endangered?
Testudodiscula testudinalis is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Testudodiscula testudinalis faces severe population decline primarily due to habitat destruction from agricultural expansion and urban development across its limited range. The species' specialized ecological requirements make it particularly vulnerable to environmental changes, while its small population size increases extinction risk from stochastic events. Collection pressure for the shell trade has further reduced already fragmented populations.
Where does Testudodiscula testudinalis live?
Testudodiscula testudinalis occurs in Portugal. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Testudodiscula testudinalis?
The main threats to Testudodiscula testudinalis are 11.2, 2.3, 6.1, and 7.1. The full IUCN-classified threat record for this species is detailed on the species page.
