Sternarchorhynchus caboclo

Unknown

Overview

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

Sternarchorhynchus caboclo faces primary threats from habitat degradation in the Amazon basin, particularly through deforestation and water pollution from agricultural runoff and mining activities. Dam construction and river channelization alter the hydrological patterns essential for this electric fish's survival. The species' restricted range in Brazilian river systems makes it especially vulnerable to localized environmental changes and water quality deterioration.

Threat summary

Habitat

This electric fish inhabits slow-moving freshwater rivers and tributaries in the Amazon basin of Brazil, typically found in areas with soft substrates and abundant aquatic vegetation. It prefers shallow waters with moderate current flow and high dissolved oxygen levels characteristic of pristine Amazonian waterways.
