Loricaria coximensis

Unknown

Overview

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

Loricaria coximensis faces severe threats from habitat degradation in the Coxim River basin of Brazil's Pantanal region. Agricultural expansion and cattle ranching have led to increased sedimentation and water pollution, while dam construction and water diversions alter the natural flow regimes essential for this armored catfish's survival. The species' extremely restricted range makes it particularly vulnerable to localized environmental changes.

Threat summary
