Bulimulus jacobi

Unknown

Overview

Bulimulus jacobi is a species of tropical air-breathing land snail, a pulmonate gastropod mollusk in the subfamily Bulimulinae.

Bulimulus jacobi faces severe threats from habitat destruction on its limited island range, where introduced grazing animals and invasive plant species have dramatically altered native vegetation communities. The species' extremely restricted distribution makes it particularly vulnerable to stochastic events and ongoing human development pressures. Climate change poses additional risks through altered precipitation patterns that could affect the moisture-dependent microhabitats essential for this terrestrial gastropod's survival.

Threat summary

Habitat

This critically endangered land snail inhabits dry coastal scrublands and rocky outcrops in the Galápagos Islands, typically found in areas with sparse vegetation and volcanic substrates. The species requires specific microhabitat conditions with adequate moisture retention and native plant cover for shelter and feeding.

Frequently asked questions

Why is Bulimulus jacobi classified as Critically Endangered?
Bulimulus jacobi 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. Bulimulus jacobi faces severe threats from habitat destruction on its limited island range, where introduced grazing animals and invasive plant species have dramatically altered native vegetation communities. The species' extremely restricted distribution makes it particularly vulnerable to stochastic events and ongoing human development pressures. Climate change poses additional risks through altered precipitation patterns that could affect the moisture-dependent microhabitats essential for this terrestrial gastropod's survival.
Where does Bulimulus jacobi live?
Bulimulus jacobi occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Bulimulus jacobi?
The main threats to Bulimulus jacobi are 8.1, ai-1, ai-2, and ai-3. The full IUCN-classified threat record for this species is detailed on the species page.
