Malarmo
Platysilurus malarmo
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
The Malarmo faces significant pressure from deforestation and agricultural expansion throughout its limited range in the Amazon basin. Dam construction and water diversions for hydroelectric projects have altered natural flow regimes in the rivers where this catfish spawns and feeds. Overfishing by local communities and commercial operations has reduced population numbers, while sedimentation from mining activities degrades the clear waters essential for the species' feeding behavior.
Habitat
The Malarmo inhabits clear, fast-flowing rivers and tributaries in the Amazon basin, preferring areas with rocky substrates and moderate to strong currents. This catfish species is typically found in well-oxygenated waters at depths of 2-15 meters, often near fallen logs or rocky outcrops that provide shelter and feeding opportunities.
