Description

The largespot river stingray is a freshwater stingray (Potamotrygonidae) from rivers of the Parana and Paraguay basin in South America. The species reaches about 40 cm across the disc and has a round, flat, brown disc with numerous pale eye-spots that camouflage it on the sandy bottom. Half-buried it searches for molluscs, crustaceans and small fish. In its whip-like tail it carries one or more venomous, serrated spines that give a very painful, slow-healing wound; it stings only in defence when touched or stepped on.
