Partula arguta
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Partula arguta faces extinction primarily due to predation by the introduced carnivorous snail Euglandina rosea, which was deliberately introduced to Pacific islands in the 1970s as a misguided biological control agent. The species has also suffered from habitat destruction through deforestation and urban development across its native range in French Polynesia. Competition from other introduced mollusks and the impacts of invasive plant species that alter native forest structure have further compromised remaining populations.
Habitat
Partula arguta inhabits native tropical forests and woodland areas in French Polynesia, typically found on vegetation and leaf litter in humid, shaded environments. The species requires specific microhabitat conditions including adequate moisture levels and native plant communities that provide both food sources and shelter.
