Jenynsia sanctaecatarinae
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Jenynsia sanctaecatarinae faces severe population decline primarily due to habitat degradation from urban development and agricultural expansion along Brazil's coastal regions. Water pollution from industrial discharge and agricultural runoff has contaminated the freshwater systems this endemic species depends upon. The species' extremely limited range makes it particularly vulnerable to localized environmental changes, with habitat fragmentation isolating remaining populations.
Habitat
This endemic Brazilian fish inhabits freshwater streams, rivers, and associated wetlands in the coastal Atlantic Forest region of Santa Catarina state. The species requires clean, well-oxygenated waters with moderate flow rates and abundant aquatic vegetation.
