Achatinella pupukanioe
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Achatinella pupukanioe faces severe population decline primarily due to predation by introduced species, particularly the rosy wolfsnail (Euglandina rosea) and various rat species that consume both adults and eggs. Habitat degradation from invasive plant species and human development has fragmented the remaining native forest areas essential for this species' survival. Climate change poses an additional threat by altering the moisture and temperature conditions required for this moisture-dependent snail species.
Habitat
This endemic Hawaiian tree snail inhabits native mesic and wet forests on the island of Oahu, typically found on native trees and shrubs in areas with high humidity and consistent moisture. The species requires intact native forest canopy that maintains the specific microclimate conditions essential for its survival and reproduction.
