Sternarchorhynchus mareikeae

Unknown

Overview

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

Sternarchorhynchus mareikeae faces primary threats from habitat degradation in the Amazon basin, where deforestation and water pollution from mining and agricultural runoff directly impact the clear, slow-moving waters this electric fish requires. Dam construction and river channelization alter the hydrological conditions essential for its specialized electroreception and breeding behaviors. The species' limited distribution range makes it particularly vulnerable to localized environmental changes and water quality deterioration.

Threat summary

Habitat

This electric fish inhabits slow-moving, clear waters of the Amazon basin, typically found in shallow areas with soft substrates and abundant aquatic vegetation. It prefers well-oxygenated environments with stable water chemistry, often associated with flooded forest margins and quiet backwaters.
