Melanorivulus egens
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Melanorivulus egens faces severe threats from habitat destruction due to urban expansion and agricultural development in its restricted range in southeastern Brazil. Water pollution from agricultural runoff and urban waste significantly degrades the shallow freshwater environments this killifish depends on for survival. The species' extremely limited distribution makes it particularly vulnerable to localized environmental changes and human activities.
Habitat
This critically endangered killifish inhabits shallow freshwater streams, pools, and wetlands in the Atlantic Forest region of southeastern Brazil. It typically occurs in slow-moving or temporary water bodies with dense aquatic vegetation and soft substrates.
