Ray identification

hi, been offered a pair of rays recently, the guy selling them says they are 'true histrix' rays, but also says they were caught in peru, which meens they can't be true histrix as they are caught in brazil.
another person who i asked says he thinks (not for definite) that they may be yepezi, but to my knowledge these are caught in venezuela.
i appreciate the fish is young and not the easiest to identify but if anyone could point me in the right direction id appreciate it!


cheers, Dave

i just need a scientific name really, i know its not histrix, as i said in the post its caught in peru, not brazil, yepezi are from venezuela.
does anyone konw what it is please?
i don't want to know what it isn't.

ok thanks, are these cheap and common rays then?
does anyone know anything about them?
also when you say yepezi do you meen ones listed as 'true yepezi'?

Dave

ok cheers they can stay where they are then!
