Rollizo

Parodon caliensis

Unknown

Overview

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

The Rollizo faces severe pressure from agricultural expansion and cattle ranching activities that degrade riparian vegetation along its native river systems in Colombia's Cauca Valley. Dam construction and water extraction for irrigation have altered natural flow regimes, while sedimentation from deforestation in surrounding watersheds degrades water quality. Urban development and industrial pollution from nearby cities further compromise the aquatic ecosystems this endemic characiform depends upon.

Threat summary

Habitat

The Rollizo inhabits clear, fast-flowing rivers and streams in the Magdalena River basin of Colombia's Cauca Valley region. This species prefers rocky substrates with moderate to strong currents and well-oxygenated waters typical of Andean foothill river systems.
