Plesiotrygon
Plesiotrygon, the antenna rays, is a small genus of freshwater stingrays in the family Potamotrygonidae endemic to the Amazon basin in South America. They are found in large rivers and the lower part of their tributaries. The maximum disc width is up to 58 cm (23 in), but both species are very long-tailed (tail length typically at least twice the disc width).
