Freshwater stingrays are native to a number of South American freshwater river systems. These rays prefer sandy substrate of calm-moving streams, tributaries, and rivers and are often found partially buried.
Coloration along the dorsal (top) half is brown, with orange to yellow eyespots, each surrounded by a black ring
Body shape is oval with a venomous spine on their tail
Eyes are slightly raised
The eye-like markings that cover their dorsal side vary in appearance and position from individual to individual and have earned this ray its other name, Ocellate stingray.
Like many other ray species, the freshwater stingray possesses a venomous, barbed tail used for defense. Their eyes are located just above their bodies and parallel to each other, giving the ray a nearly 360-degree view of their surroundings.
The International Union for Conservation of Nature (IUCN) has listed the freshwater stingray population as Data Deficient due to the poor life history and population data available for this species.
