I looked on google, but there was not much there. Looking to get some info on them as far as their marketability.
PARATRYGON ORBICULARIS
- Thread starter N-E Cichlids
- Start date
Whered you get the name P. Orbicularis??
Looks like an outdated latin name.. Did an exporter throw this label on the fish?
The only Paratrygon I am aware of for export is Paratrygon Aireba, or the "Ceja" ray.. (translates: eyebrow) They are in the small-eyed ray family, very hard to keep. Ambush predators, finicky eaters is biggest downfall, and are sensitive to water quality. They also get 3'+ across (?), so it ruins their marketability..
It is sometimes confused with Potamotrygon Brachyura, another large ray with a slight mottled pattern and distinct body shape.. Brachyura is often referred to as the "apple" ray, and come from the southern regions of SA. The rays are easily distinguished by eye structure, small eye family vs. large eye family..
You can read up more on the Paratrygon family on my website link below..

The only thing I could find with Orbicularis is this;
INDETERMINATE SPECIES
RAJA ORBICULARIS Bloch & Schneider 1801
Aiereba MARCGRAVE 1648 (Brazil ) Nat. Hist. of Brazil. This is not a Potamotrygonid, but an unidentifiable marine species of the genus Dasyatis.

The common name they called it was Antenna Ray. PARATRYGON ORBICULARIS was the scientific name given. Here is a link of what I have found. Second picture down. Sort of looks like what my supplier showed me.

Plesiotrygon Iwamae
is the antenna ray.. same deal.. small eyes, finicky eater, ambush predator, gets huge..
The paratrygon ID was either out of date or someone was wayyy off..
Apparently there are 2 variations of the Antenna ray.. The common one that gets very large, and then the "Black-tailed" Antenna ray, which is supposed to stay smaller in the 12-14" range.. However, I have never seen evidence of either species being distinct, and it's more than likely a mis-identification issue by the scientists, who based the perspective maximum size on the holotype they used to ID this "black-tailed" variant.
If it has a black tail, and has a pattern like a retic.. let me know. I want it
PS. FYI ~ The pix you linked up was stolen from a book.. so that website might not be very reliable.
