Potamotrygon is a genus of freshwater stingrays in the family Potamotrygonidae native to the rivers of South America,[1] and sometimes seen in the aquarium trade.[2]
Like other stingrays, the fishes of this genus have venomous barbs at the base of their tails, and their stings are dangerous to humans.[2] It is said that the natives of South America fear the stingray more than they do fear the piranha.[3]
Potamotrygon vary considerably in color, pattern and size, with the maximum disc width ranging from 31 cm (1 ft) in P. wallacei to 1.5 m (5 ft) in P. brachyura.[4][5]
