Aphyosemion edeanum

Unknown

Overview

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

Aphyosemion edeanum faces severe pressure from habitat degradation in its limited range within the Cross River basin of Nigeria and Cameroon. Agricultural expansion and urban development have fragmented the small forest streams and seasonal pools this killifish depends on for breeding. Water pollution from agricultural runoff and domestic waste further compromises the quality of remaining aquatic habitats, while deforestation reduces the forest canopy cover that maintains optimal water temperatures and chemistry.

Threat summary

Habitat

This killifish inhabits small forest streams, temporary pools, and swampy areas within the Cross River drainage system of southeastern Nigeria and southwestern Cameroon. It prefers shallow, slow-moving waters with dense vegetation cover and soft, acidic conditions typical of West African rainforest environments.
