Kryptolebias brasiliensis
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Kryptolebias brasiliensis faces severe threats from coastal development and urbanization along Brazil's Atlantic coast, which destroys the shallow mangrove pools and tidal areas essential for its survival. Water pollution from agricultural runoff and urban discharge degrades the brackish water quality these fish require. Climate change poses additional risks through sea level rise and altered precipitation patterns that could eliminate the species' specialized microhabitats.
Habitat
This species inhabits shallow, temporary pools in mangrove areas and coastal wetlands along Brazil's Atlantic coast. It requires brackish water environments with specific salinity levels and can survive in ephemeral pools that periodically dry up.
