Hirasea operculina

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Hirasea operculina faces severe threats from habitat destruction as Japan's coastal and lowland forests are converted for urban development and agriculture. The species' limited dispersal ability as a terrestrial gastropod makes it particularly vulnerable to habitat fragmentation, preventing recolonization of disturbed areas. Climate change poses additional risks through altered precipitation patterns that could affect the moist microhabitats essential for this snail's survival.

Threat summary

Habitat

This endemic Japanese land snail inhabits moist deciduous and mixed forests, particularly in coastal and lowland areas where it requires stable microhabitats with consistent moisture levels. The species is typically found among leaf litter and under logs in well-shaded forest environments.
