The next freshwater Chondrichthyan that The Fins United Initiative wants to introduce you is Amanda’s river stingray (Potamotrygon amandae). In the Potamotrygonidae (River stingrays) family, the Greek words “potamos” and “trygon” mean ‘river’ and ‘a sting ray’ respectively. Named for Amanda Lucas Gimeno, hence amandae, they are known from the Paraná-Paraguay basin in South America.

Measuring at 31.2 cm disc width (DW) for males and 34.1 cm DW for females. It is a gray-dark brown color with bicolored ocelli on the top part of their disc, they sport gray-ish tummies. Nothing else is known about these animals, and the IUCN has not assessed these animals.
