Sternarchorhynchus jaimei

Declining

Overview

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

Sternarchorhynchus jaimei faces severe threats from deforestation and agricultural expansion in the Amazon Basin, which fragments its riverine habitat and reduces water quality. Dam construction and water diversion projects further degrade the slow-moving waters this electric fish requires for survival. The species' extremely limited range makes it particularly vulnerable to localized environmental changes and pollution from mining activities.

Threat summary

Habitat
