for what i think is, there will be fan for pure bloods and hybrid, in the asia market as long as the rays is beautiful, pure or hybrid, that's not an issue!

We seen pure going for like 20-30k and seen hyrbids with that kinda price... so......

and like rayman said's, who knows if the wild caught p14 are also hybrids?

I personally import before leohen from the wild.

willing buyer willing seller, if the ray is beautiful and the price is what you can afford, just buy it or no.l

Hi Matt,

Zoodiver;2210326; said:
Which DNA method of testing was used?
I was under the impression no documentaion was around to show wild hybrids.
COI
Here is the pdf:

A test of the utility of DNA barcoding in the radiation of the freshwater
stingray genus Potamotrygon(Potamotrygonidae, Myliobatiformes)


Page 329 bottom right:

Potamotrygon motoro, Potamotrygon scobina, and Potamotrygon orbignyi

We found that three of the four species with broadest distribution in the Amazon basin (the fourth species Paratrygon aiereba was not included in this study), species which also are highly polymorphic, were not reciprocally monophyletic, and extensively shared haplotypes among species. Haplotype sharing may indicate that i) taxonomic validity of these species should be reassessed; ii) lineages did not have enough time to reach reciprocally monophyly; iii) hybridization; or iv) combination of these factors (Moritz and Cicero, 2004).
