Sometimes called the bearded toadheads but better known by their scientific name of Phrynops this genus of turtles has often been a bit of a dumping ground for the short-necked South American turtles of the family Chelidae.

The genus is widely distributed in South America found in the Orinoco to Amazon and São Francisco to Paraná and adjacent river basins of Colombia, Venezuela, the Guianas, Brazil, Paraguay, Uruguay and northeastern Argentina (Iverson, 1992).[4]
