Cnesterodon iguape
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Cnesterodon iguape faces severe threats from urban development and agricultural expansion in the coastal regions of southeastern Brazil, which have dramatically reduced and fragmented its freshwater habitat. Water pollution from agricultural runoff and urban discharge has degraded the quality of remaining streams and rivers where this small livebearing fish occurs. The species' extremely limited range makes it particularly vulnerable to local environmental changes and habitat destruction.
Habitat
This species inhabits small freshwater streams and rivers in the coastal Atlantic Forest region of southeastern Brazil. It typically occurs in shallow, slow-moving waters with vegetation cover in areas that have experienced significant human modification.
