Description

The ocellate river stingray is a freshwater stingray (Potamotrygonidae) from northern and central South America. The species has a flattened, disc-shaped body with a grey-brown upper side studded with conspicuous, yellow-ringed eyespots. It lives on sand and mud bottoms of rivers, lakes and lagoons, where it often buries itself. It feeds on crustaceans, molluscs, worms and small fishes. The tail bears a serrated, venomous spine that can give a deep, very painful and notorious stab wound; take care where you step in shallow water.
