​The ocellate river stingray (Potamotrygon motoro), is also known as the 'peacock-eye stingray' or the 'black river stingray.' It is a beautiful species of freshwater stingray in the Potamotrygonidae family- yup, a whole family of FRESHWATER STINGRAYS! In fact, this was the first species described in that family! It is also the most widespread. You can find it throughout much of the Río de la Plata, Amazon, Mearim and Orinoco basins in South America. You may have seen these animals before in aquariums.
