Those look to have a striking resemblance to Snow Leopards in their juvenile state, however this species is also known as Potamotrygon "sp" Xingu as it hails from that river, maybe it is found further a field so to speak?
Its also worth mentioning that Snow Leopards have multiple spines running down the tail as seen in leopoldi (P13) . If there is just one single row then they could be one of the orbignyi complex, there is a lot of work to be done regarding positive id on this species imo as the patterns are just too variable not to mention found throughout many South American countries.

There's just a single row of spines ... so def a orb ... and it came from Araguaia river as well ... Thanks a lot ...
 
Is that a Jau Catfish Zungaro zungaro (formerly Paulicea lutkeni) nestled beside that wood ?

Yeap ..; There's a Zungaro zungaro right next to them ... I have both Zungaros, a Zungaro zungaro and a Zungaro jahu ... Zungaro jahu tends to be more aggressive and territorial that Z.zungaro ...
