Flax Snail

Placostylus koroensis

Unknown

Overview

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

Placostylus koroensis faces severe threats from habitat destruction as native forests on Koro Island are cleared for agriculture and development. The species' extremely limited range makes it particularly vulnerable to introduced predators, especially rats and other invasive mammals that prey on eggs and juveniles. Climate change poses an additional threat through altered rainfall patterns that could disrupt the humid forest conditions essential for this land snail's survival.

Threat summary

Habitat

This endemic land snail inhabits the humid native forests of Koro Island in Fiji's Lomaiviti archipelago. It requires moist forest floor conditions with abundant leaf litter and decaying organic matter typical of tropical island forest ecosystems.
