Achatinella turgida
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Achatinella turgida faces severe population decline primarily due to habitat destruction from urban development and invasive plant species that alter native forest composition. Introduced predators, particularly the rosy wolf snail (Euglandina rosea) and various ant species, have devastated remaining populations through direct predation. Climate change compounds these pressures by shifting rainfall patterns and temperature ranges that affect the cool, moist microhabitats essential for this species' survival.
Habitat
This endemic Hawaiian tree snail inhabits native mesic and wet forests on Oahu, typically found on native trees and shrubs in cool, moist environments between 300-800 meters elevation. The species requires specific microhabitat conditions with high humidity and stable temperatures provided by intact native forest canopy.
