Puma
Otorongo (Jaguar)
Tigrillo
all Castexi.. or mis-labeled as something.
Katfishguy's link is to a hybrid ray, but the 'mantilla' type rays can sometimes be called 'Puma'..
Killerlexus' fish looks more like an Orbignyi or Humerosa, but could be labeled as the false Yepezi out of Peru..
What country is it coming from? Could be an un_ID'ed ray or a sporatically patterned Motoro, but I can almost guarantee, especially if from Peru, it is a Castexi variant.. I have seen 'Puma' used on a number of Castexi variants, especially ones they sometimes also call Motelo (turtle) among others..
Could be just about anything with Mis_ID's and common names.. I saw a pix of a Puma ray a while back but can't find it.
