Ocellate river stingray
The ocellate river stingray is a freshwater stingray with a round, flat body and yellow-orange spots on its back. It lives in rivers across much of tropical and subtropical South America. It is the most widespread member of its family, and it is sometimes kept in aquaria.1

- Its disc is roughly circular in shape.1
- Its eyes are raised from the upper surface of the disc.1
- The back is typically beige or brown, with numerous yellow-orange spots that have dark rings.1

The largest recorded weight is 34.2 kg, but the official IGFA record is 12.59 kg.1
It is one of the most popular freshwater stingrays kept in aquaria, and it breeds readily in captivity.1
Populations vary so much in appearance that scientists have grouped several similar species together as a species complex.1
