Knodus dorsomaculatus
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Knodus dorsomaculatus faces severe pressure from deforestation and agricultural expansion throughout its limited range in the Amazon Basin. Mining activities and infrastructure development have degraded critical headwater streams where this small characin depends on pristine water quality. The species' restricted distribution makes it particularly vulnerable to localized habitat destruction, with several known populations already eliminated by human activities.
Habitat
This small freshwater fish inhabits clear, fast-flowing streams and tributaries in pristine Amazon rainforest areas. It requires well-oxygenated waters with intact riparian vegetation and shows strong preference for headwater systems with rocky or sandy substrates.
