Opanara duplicidentata

Unknown

Overview

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

Opanara duplicidentata faces severe threats from habitat destruction and degradation of its limited freshwater environments. The species' extremely restricted range makes it particularly vulnerable to local environmental changes, pollution, and human activities that alter water quality and flow patterns. Climate change poses additional risks through altered precipitation patterns and temperature fluctuations that could disrupt the delicate aquatic ecosystems this endemic species depends upon.
