Listrura costai

Unknown

Overview

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

Listrura costai faces severe threats from habitat degradation in Brazil's Atlantic Forest region, where deforestation and agricultural expansion have fragmented its freshwater environments. Dam construction and water pollution from agricultural runoff further compromise the pristine stream conditions this endemic catfish requires. The species' extremely limited range makes it particularly vulnerable to localized environmental changes.

Threat summary
