Simpsonichthys nigromaculatus

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Simpsonichthys nigromaculatus faces severe habitat degradation from agricultural expansion and cattle ranching across Brazil's Cerrado savanna. The species' dependence on seasonal temporary pools makes it extremely vulnerable to hydrological changes caused by water extraction and altered precipitation patterns. Urban development and infrastructure projects continue to fragment and destroy the ephemeral wetland systems essential for this killifish's breeding cycle.

Threat summary

Habitat

This killifish inhabits temporary seasonal pools and shallow wetlands within Brazil's Cerrado savanna ecosystem. The species depends entirely on ephemeral water bodies that fill during rainy seasons and dry completely during drought periods.
