The largespot river stingray is a freshwater stingray with a flat, round body covered in dense spots. It lives in the rivers of tropical and subtropical South America, mainly the Paraná-Paraguay river basin and parts of the upper Amazon. It is sometimes kept in aquariums, but it needs a very large tank.1

Xibaar

1

Its natural range was once cut off from the upper Paraná basin by the Guaíra Falls. After the Itaipu Dam was built, the falls disappeared, which let this species and several others spread into that area.1

2

Its spotted pattern is so variable that one pattern was once described as a separate species, P. castexi, and another as P. menchacai. All of these are now treated as variants of this species.1

3

It is sometimes kept in aquariums, but it needs a very large tank because of its size.1

Tasukatu léeb

Xalaat bu juum: The 'tiger stingray' is the same animal as the largespot river stingray.

Dëgg: The tiger stingray is a separate species, P. tigrina, which was only scientifically described in 2011. It was earlier mistaken for P. menchacai, which is a name for this species.1
