Plesiotrygon, the antenna rays, is a small genus of freshwater stingrays in the family Potamotrygonidae endemic to the Amazon basin in South America.[1][2] They are found in large rivers and the lower part of their tributaries.[2] 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).[1][2]
Plesiotrygon are occasionally kept in aquariums and both species have been bred in captivity, but they are sensitive and the tail is easily damaged.[3][4]
Species
There are two recognized species:[1]
- Plesiotrygon iwamae R. de S. Rosa, Castello & Thorson, 1987 (long-tailed river stingray, antenna ray)
- Plesiotrygon nana M. R. de Carvalho & Ragno, 2011 (black-tailed antenna ray, dwarf antenna ray)
