Boninena callistoderma

Unknown

Overview

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

Boninena callistoderma faces severe threats from habitat destruction on the Bonin Islands, where introduced species have dramatically altered native forest ecosystems. The species' extremely limited range makes it particularly vulnerable to environmental changes, with invasive plants and grazing animals degrading the humid forest understory where these snails depend on specific microhabitat conditions. Climate change poses additional risks through altered precipitation patterns that could disrupt the moisture-dependent lifecycle of this endemic gastropod.

Threat summary

Habitat

This endemic land snail inhabits the humid native forests of the Bonin Islands (Ogasawara Islands), Japan, where it requires specific microhabitat conditions in the forest understory. The species depends on stable moisture levels and native vegetation structure that provides appropriate shelter and food sources.

Frequently asked questions

Why is Boninena callistoderma classified as Endangered?
Boninena callistoderma is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. Boninena callistoderma faces severe threats from habitat destruction on the Bonin Islands, where introduced species have dramatically altered native forest ecosystems. The species' extremely limited range makes it particularly vulnerable to environmental changes, with invasive plants and grazing animals degrading the humid forest understory where these snails depend on specific microhabitat conditions. Climate change poses additional risks through altered precipitation patterns that could disrupt the moisture-dependent lifecycle of this endemic gastropod.
Where does Boninena callistoderma live?
