Potamotrygon amazona, the Upper Amazon raspy freshwater stingray, is a type of freshwater tropical stingray found in the state of Amazonas and Roraima, Brazil. [1] [2]
This species can be distinguished from its congeners through several characteristics: sturdy and thick disc; dark brown to gray dorsal color; body covered with many small whitish-beige irregular spots with small ocelli sometimes present; disc entirely covered by denticles; very prickly robust, wide, and long tail; and relatively short cartilaginous rod. [2] It can reach the maximum size of 40 - 58 cm disc width (DW). [2]
This stingray is endemic to the freshwater basins of Rio Jutai and Rio Juruá in Amazonas, and Rio Branco in Roraima. [1] [2] Major threats might include illegal deforestations, albeit not significant yet due to its remote habitats. [1]
