The raspy river stingray, mosaic stingray or arraia (Potamotrygon scobina) is a species of freshwater fish in the family Potamotrygonidae. This stingray is endemic to the Amazon basin in Brazil, [1] where known from the AmazonPará River ( Belém to near the confluence with the Putumayo River), the Madeira River basin, Uatumã River and lower Tocantins River. [2]

It reaches up to 69.1 cm (2.27 ft) in disc width and 132.5 cm (4.35 ft) in total length. [1] It is fairly common, but threatened by habitat loss. [1] It is part of a group consisting of five allopatric Amazonian stingrays, the others being P. adamastor ( Uraricoera River), P. amazona ( Juruá, Jutaí and Rio Negro), P. garmani (mid to upper Tocantins River) and P. limai ( Jamari River). [2] These all have three angular cartilages (as opposed to the one or two seen in other species in the genus). [2]
