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]
Description
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]
Habitat & distribution
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]
