Hirasea acutissima

Unknown

Overview

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

Hirasea acutissima faces severe population decline primarily due to habitat destruction from urban development and agricultural expansion across its limited range in Japan. The species' restricted distribution makes it particularly vulnerable to localized environmental changes, while invasive plant species alter the forest floor microhabitat essential for this terrestrial gastropod. Climate change poses an additional threat through altered precipitation patterns that affect the moist conditions required for survival.

Threat summary

Habitat

This endemic Japanese land snail inhabits moist deciduous and mixed forests, typically found in leaf litter and under fallen logs in mountainous regions. The species requires stable microhabitat conditions with consistent moisture levels and organic matter accumulation on the forest floor.
