The Otuno (scientific name: Olivaichthys viedmensis) is a special type of velvet catfish. This fish is found only in Argentina, which means it is endemic to that country. You can find the Otuno swimming in the Rio Negro and its smaller rivers (called tributaries).
The Otuno can grow to be about 32.4 centimeters (about 12.7 inches) long. This measurement is usually taken from the tip of its nose to the base of its tail, which is called its Standard Length (SL).

What is the Otuno?
The Otuno is a type of catfish, known for its smooth, "velvety" skin instead of scales. It belongs to a group of fish that often have whiskers, called barbels, around their mouths. These barbels help them feel and taste their way around in the water, especially in murky conditions.
Where Does the Otuno Live?
The Otuno lives in freshwater environments in Argentina. Its main home is the Rio Negro, a large and important river in the country. It also lives in the smaller streams and rivers that flow into the Rio Negro. These rivers provide the perfect habitat for the Otuno, with places to hide, find food, and lay eggs.
What Does the Otuno Look Like?
Like many catfish, the Otuno likely has a flattened head and a body that tapers towards the tail. Its color probably helps it blend in with the riverbed, perhaps shades of brown, gray, or olive green. The "velvet" part of its name suggests its skin is very smooth to the touch, unlike fish with rough scales.
Life of an Otuno
Just like other fish, the Otuno has a life cycle that involves growing from an egg to an adult.
Diet and Feeding
The Otuno is likely an omnivore or a carnivore, meaning it eats a mix of things. It might feed on small insects, tiny crustaceans, or even smaller fish that live in the river. Its barbels are very useful for finding food in the dark or muddy waters of its habitat.
Reproduction and Life Cycle
Fish like the Otuno usually reproduce by laying eggs. The female fish lays eggs, and the male fish fertilizes them. These eggs then hatch into tiny fish called fry. The fry grow into juveniles, and eventually become adult Otunos, ready to reproduce themselves. The specific details of the Otuno's reproduction might depend on the season and water conditions in the Rio Negro.
Why is the Otuno Important?
Every species, including the Otuno, plays a role in its ecosystem. The Otuno helps keep the river healthy by being part of the food chain. It might eat smaller organisms, and in turn, it could be a food source for larger animals like birds or other fish.
Conservation
Because the Otuno is endemic to Argentina, it means it's found nowhere else in the world. This makes it very special and important to protect. Scientists and conservationists work to make sure the Otuno's habitat, the Rio Negro and its tributaries, stays clean and healthy. Protecting the river helps protect all the animals that live there, including the unique Otuno.
