Diapoma pyrrhopteryx

Unknown

Overview

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

Diapoma pyrrhopteryx faces severe population decline primarily due to habitat degradation from agricultural expansion and cattle ranching in the Paraná River basin. Water pollution from agricultural runoff and urban development has significantly impacted water quality in its native streams. Dam construction and water extraction for irrigation have altered natural flow regimes, fragmenting populations and reducing suitable breeding habitat.

Threat summary

Habitat

This small characin fish inhabits clear, shallow streams and tributaries within the Paraná River basin in South America. It prefers well-oxygenated waters with sandy or rocky substrates and moderate current flow, typically found in areas with riparian forest cover.
