Boninosuccinea punctulispira

Unknown

Overview

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

Boninosuccinea punctulispira faces severe habitat degradation from invasive plant species that alter the native forest understory composition essential for this endemic land snail. The species' restricted range on the Bonin Islands makes it particularly vulnerable to introduced predators, including flatworms and other non-native invertebrates that prey on native gastropods. Climate change poses an additional threat through altered precipitation patterns that could disrupt the humid microhabitats this species requires for survival.

Threat summary

Habitat

This endemic land snail inhabits the humid understory of native forests on the Bonin Islands (Ogasawara Islands), Japan, where it requires specific microhabitat conditions including leaf litter and decaying organic matter. The species depends on the stable moisture levels and temperature regulation provided by intact native forest canopy.
