Heliotrygon rosai, the Rosa's round ray, is a species of freshwater fish in the family Potamotrygonidae. It is native to the Amazon basin (Marajó to Peru) in South America.[1] Its maximum disc width is 80 cm (2.6 ft) and the stinger is greatly reduced, rendering it virtually harmless.[1] It has not been evaluated by the IUCN red list.[2]
