02Description

Species Profile

Species profile data sourced from the IUCN Red List of Threatened Species.

Sturisomatichthys frenatum faces severe threats from habitat degradation due to deforestation, agricultural expansion, and water pollution in its native South American river systems. Dam construction and water diversions have fragmented populations and altered critical flow regimes. The species' limited distribution and specialized habitat requirements make it particularly vulnerable to environmental changes.
