Freshwater aquariums

River stingrays are neotropical freshwater fishes, of the Potamotrygonidae family (order Rajiformes).

They are living in rivers that drain into the Caribbean, and into the Atlantic as far south as the Río de la Plata in Argentina. Generally, each species is native to a single river basin.

River stingrays are almost circular in shape, and range in size from Potamotrygon schuhmacheri, which reaches 25 cm in diameter, to the ocellate river stingray, Potamotrygon motoro, which grows up to a metre in diameter. The dorsal surface is covered with denticles (sharp tooth-like scales).

They have a poisonous caudal sting, and are one of the most feared freshwater fishes, in the neotropical region, sometimes more feared than piranhas and electric eels. However, they are not dangerous unless stepped on or otherwise threatened.

River stingrays are the only family of batoids to be restricted to fresh water habitats.
