Simpsonichthys parallelus
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Simpsonichthys parallelus faces severe threats from habitat degradation in Brazil's Cerrado savanna, where agricultural expansion and cattle ranching have destroyed much of its seasonal wetland habitat. The species' dependence on temporary pools that fill during rainy seasons makes it particularly vulnerable to hydrological changes caused by dam construction and water diversion for irrigation. Climate change poses an additional threat by altering precipitation patterns that are critical for the species' breeding cycle.
Habitat
This annual killifish inhabits temporary seasonal pools and shallow wetlands in the Brazilian Cerrado savanna. The species depends on ephemeral water bodies that form during the rainy season and dry completely during drought periods.
