Listrura tetraradiata

Unknown

Overview

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

Listrura tetraradiata faces severe threats from habitat degradation in its restricted range within Brazilian Atlantic Forest streams. Deforestation, agricultural expansion, and urban development have fragmented and polluted the small headwater streams this catfish depends on. Water quality deterioration from agricultural runoff and sedimentation poses additional risks to this endemic species with extremely limited distribution.

Threat summary
