Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Rhizosomichthys totae faces severe threats from habitat degradation in Colombia's Magdalena River basin, where agricultural expansion and urban development have dramatically altered its freshwater environment. Water pollution from agricultural runoff and industrial discharge has compromised water quality in its limited range. The species' extremely restricted distribution makes it particularly vulnerable to localized environmental changes, with dam construction and water extraction further fragmenting its already limited habitat.
Habitat
This freshwater fish is endemic to the Magdalena River basin in Colombia, inhabiting specific riverine environments with particular water chemistry and flow characteristics. It requires clean, well-oxygenated waters with specific substrate conditions typical of neotropical river systems.
