Simpsonichthys boitonei

Unknown

Overview

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

Simpsonichthys boitonei faces severe threats from habitat degradation in Brazil's Cerrado savanna, where agricultural expansion and cattle ranching have dramatically reduced suitable wetland areas. The species' dependence on seasonal pools makes it particularly vulnerable to hydrological changes caused by water extraction and altered precipitation patterns. Urban development and infrastructure projects further fragment the remaining habitat patches essential for this endemic killifish's survival.

Threat summary

Habitat

This endemic Brazilian killifish inhabits temporary pools and seasonal wetlands within the Cerrado savanna ecosystem. The species depends on ephemeral water bodies that form during the rainy season and dry up during the dry season, requiring specific hydrological cycles for reproduction and survival.
