Rachoviscus crassiceps

Unknown

Overview

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

Rachoviscus crassiceps faces significant pressure from habitat degradation in Brazil's Atlantic Forest region, where deforestation and agricultural expansion have fragmented its freshwater environments. Water pollution from agricultural runoff and urban development further compromises the quality of streams and rivers this species depends upon. The species' restricted range makes it particularly vulnerable to localized environmental changes and human activities.

Threat summary

Habitat

This small freshwater fish inhabits clear, fast-flowing streams and rivers in the Atlantic Forest region of southeastern Brazil. It typically occurs in well-oxygenated waters with rocky or sandy substrates, often in areas with moderate to strong current flow.
