Hollandichthys taramandahy
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Hollandichthys taramandahy faces severe pressure from deforestation and agricultural expansion throughout its limited range in southeastern Brazil's Atlantic Forest region. Dam construction and water diversions for hydroelectric projects have significantly altered natural flow regimes in the coastal river systems this species depends upon. Urban development and pollution from agricultural runoff continue to degrade water quality in remaining habitat fragments.
Habitat
This endemic freshwater fish inhabits clear, fast-flowing streams and small rivers within Brazil's Atlantic Forest biome, particularly in coastal drainage systems of southeastern Brazil. The species requires well-oxygenated waters with rocky substrates and intact riparian forest cover.
