Ogasawarana yoshiwarana
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Ogasawarana yoshiwarana faces severe threats from invasive species, particularly the introduced flatworm Platydemus manokwari, which preys directly on native land snails. Habitat degradation from invasive plants and human development on the Ogasawara Islands has further reduced suitable forest environments. The species' extremely limited range makes it vulnerable to stochastic events and local extinctions.
Habitat
This endemic land snail inhabits the native forests of the Ogasawara Islands (Bonin Islands), Japan, particularly in areas with dense leaf litter and humid microhabitats. It requires undisturbed forest environments with native vegetation that provide appropriate moisture levels and shelter.
