The Yaqui chub is a small freshwater fish of the carp family. It lives in rivers and streams of the Yaqui River basin in southern Arizona and northern Mexico.
The Yaqui chub differs from related species by its purple body tint and adaptation to drying rivers. It is important as part of the food chain and as an indicator of freshwater ecosystem health.
Immature form that undergoes metamorphosis before adulthood.
