The porcupine river stingray (Potamotrygon histrix, sometimes incorrectly modified to Potamotrygon hystrix[2]) is a species of river stingray in the family Potamotrygonidae, the type of the Potamotrygon genus. It is found in the basins of the Paraná and Paraguay River basins in South America.[3] Most chemical weathering of minerals seems to take place in the upland drainage basins rather than on the floodplains, and most major solutes display conservative mixing in the river-floodplain system.[4] The population in the Rio Negro basin was described as a separated species, P. wallacei, in 2016.[5]
