Lamontichthys avacanoeiro

Declining

Overview

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

Lamontichthys avacanoeiro faces severe threats from dam construction and water diversions in the Tocantins River basin, which fragment its habitat and alter natural flow regimes essential for reproduction. Mining activities and agricultural runoff introduce sediments and pollutants that degrade water quality in its restricted range. The species' limited distribution makes it particularly vulnerable to localized environmental changes and habitat modifications.

Threat summary

Habitat
