Opanara megomphala

Unknown

Overview

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

Opanara megomphala faces severe threats from habitat destruction due to agricultural expansion and urban development across its limited range in French Polynesia. The species' restricted distribution makes it extremely vulnerable to environmental changes, with introduced plant species altering the native vegetation structure essential for its survival. Climate change poses additional risks through altered precipitation patterns affecting the humid microhabitats this endemic snail requires.
