Potamorhina laticeps

Unknown

Overview

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

The Manamana faces severe pressure from dam construction and river channelization throughout the Amazon basin, which fragments its riverine habitat and alters natural flow patterns essential for its lifecycle. Overfishing and bycatch in commercial fisheries targeting other species pose additional threats, while deforestation in surrounding watersheds increases sedimentation that degrades water quality in its preferred clear-water habitats.

Threat summary

Habitat

The Manamana inhabits clear and white-water rivers throughout the Amazon basin, preferring areas with moderate current and sandy or rocky substrates. It is typically found in main river channels and larger tributaries, often near confluences where different water types meet.
