About the Olivaichthys cuyanus

The Olivaichthys cuyanus is a fascinating fish. It belongs to a group called "velvet catfish." These fish often have smooth, velvety skin instead of scales, which is how they get their name. They are usually bottom-dwellers, meaning they live near the riverbed.

Where it Lives

This particular fish is a true native of Argentina. It makes its home in the freshwater rivers and streams of the country. The main places where it lives are the Colorado River and all the smaller rivers that flow into it. It also lives in another big river system called the Desaguadero-Salado basin. These rivers provide the perfect environment for the Olivaichthys cuyanus to thrive.

What it Looks Like

The Olivaichthys cuyanus is a medium-sized fish. It can grow to be almost 22 centimeters long. That's about the length of a standard pencil! Like other catfish, it likely has whiskers, called barbels, around its mouth. These barbels help the fish feel and taste its way around in the water, especially when looking for food in murky river bottoms.
