Achatinella apexfulva

Unknown

Overview

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

Achatinella apexfulva faces severe population decline primarily due to predation by introduced species, particularly the rosy wolfsnail (Euglandina rosea) and rats, which 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 endemic Hawaiian tree snail.

Threat summary
