FW Ray Species Found in Captivity

[Cowturtle]

As far as I know, there are otorongo, snow leopard, castexi, menchachai/tiger, and falkneri rays, all of which fall under none of the species I had listed above from the book. This gets confusing, I'll figure those out in the morning.
I'm sure there are others, too.

P-numbers go up to 62 I believe, so that might help as well. I think it's doable, but it'll take some work.

Yep many P#s aren't actually species just variants I found the full list. Although without pictures it's not all that helpful with some of the stranger morphs.

Very informative! Thank you for posting this. I have now learned that I have a breeding pair of P6!!!

 

[Oompa Loompa]

Here's what I've determined so far:

Potamotrygon motoro - P1, P3, P5, P44
Potamotrygon ocellata - P2
Potamotrygon schroederi - P4, P40, P45
Potamotrygon hystrix - P6, P60
Potamotrygon scobina - P7, P37, P38, P39
Potamotrygon orbignyi - P9, P11, P42, P47
Potamotrygon humerosa - P10
Potamotrygon henlei - P12
Potamotrygon leopoldi - P13, P62
Potamotrygon albimaculata - P14
Plesiotrygon iwamae - P15, P16
Plesiotrygon nana - P17, P18
Potamotrygon humerosa - P23, P46, P61
Potamotrygon falkneri - P25, P26, P27, P28, P29, P30, P31, P32, P33, P34, P35, P36, P49, P50, P51, P52, P53, P54
Potamotrygon signata - P41, P48
Potamotrygon yepezi - P55
Paratrygon aeireba - P56, P57
Heliotrygon gomesi - P58
Heliotrygon rosai - P59
Potamotrygon sp. "Orange" - P22
Potamotrygon sp. "Marmor" - P8, P24
Potamotrygon sp. "Mantilla" - P19, P20, P21
Potamotrygon sp. "Chocolate" - P43

That's my interpretation of the P-system thus far. P. sp. "Orange" is a Peruvian species from what I can tell, I have no images of it but based on the short description of its range and color, my guess is that it would either fall under P. falkneri or P. motoro.
I have seen and heard nothing of P. sp. "Marmor", so I can't make any conclusions on that species so far.
P. sp. "Mantilla" and "Chocolate" are both Brazilian species, I'll go over what I think they could be in a new post though. There are 24-some species of Potamotrygon in Brazil.

Brazilian species of Potamotrygon are as follows (from Fishbase):

• Potamotrygon adamastor (used to be considered P. scobina, new spp. as of 2017)
• Potamotrygon albimaculata
• Potamotrygon amandae
• Potamotrygon amazona (used to be considered P. scobina, new spp. as of 2017)
• Potamotrygon brachyura
• Potamotrygon constellata
• Potamotrygon falkneri
• Potamotrygon garmani (used to be considered P. scobina, new spp. as of 2017)
• Potamotrygon henlei
• Potamotrygon humerosa
• Potamotrygon hystrix
• Potamotrygon jabuti
• Potamotrygon leopoldi
• Potamotrygon limai
• Potamotrygon motoro
• Potramotrygon ocellata
• Potamotrygon orbignyi
• Potamotrygon pantanensis
• Potamotrygon rex
• Potamotrygon schroederi
• Potamotrygon schuhmacheri
• Potamotrygon scobina
• Potamotrygon signata
• Potamotrygon wallacei

Now, let's start with Potamotrygon sp. "Chocolate". There is actually a bit of information about this ray - it's described as having brown skin with large orange spots, meaning it could be P. motoro or P. ocellata, essentially. However another note is that this ray reaches 40+ cm in disc width - P. ocellata is not known to reach over 30 cm at the absolute most (coming from Jeff Rapps). So, we can assume that P. sp. "Chocolate" is actually just a variant of P. motoro, found in Brazil which makes it very difficult to find. I will update the list as such.

I did find that P. sp. "Marmor" is also known as sp. "Brasil". This is a Brazilian species which grows to 60+ cm across the disk. I have zero pictures of this ray so far, and no other information yet. This will be a difficult one to identify.

I am interested to hear what people's general consensus on the Mantilla Rays is. Are they a hybrid, is it just a name thrown out there, is it an actual species/type locality from Brazil that's just no longer exported?

Interested to hear opinions.

[Oompa Loompa]

These are updates on the species with no P-number.

Potamotrygon sp. "Pearl" - reclassified, now known as P. jabuti as of 2016
Potamotrygon sp. "Peru" - unknown
Potamotrygon Reticulata - reclassified to P. orbignyi
Potamotrygon cf. Hystrix - "Peru" - assuming this is just P. hystrix
Potamotrygon Histrix - "Argentina" - assuming this is just P. hystrix
Potamotrygon Yepezi - "Venezuela" - assuming this is just P. yepezi
Potamotrygon cf. Yepezi - "Peru" - assuming this is just P. yepezi
Potamotrygon Menchacai - reclassified to P. falkneri
Potamotrygon Ocellata
Potamotrygon Garrapa - considered to be P. motoro
Potamotrygon Constellata
Potamotrygon Brachyura
Potamotrygon Marinae
Potamotrygon Magdelenae
Potamotrygon Sp.aff.dumerilii - reclassified to P. orbignyi
Potamotrygon Schuemacheri

All the species without notes on them are still listed as their respective species. There are a few new species that aren't on that list as well

https://www.ruinemans.com/de-DE/5144/marmor.susswasserrochen.html I found this on "Marmor" they have it's latin name as a hystrix but it looks more like a motoro/mantilla hybrid.

Also I think snow leopards might be a scobina variant after looking up scobina from the xingu.
Although officially they're still Potamotrygon sp xingu.

Agreed on the Marmor ray - we'll let some more people weigh in before officially including them under any species, if I even do decide to. Same with Snow Leopards, officially they are "sp. Xingu" but to me they look like a heavily patterned scobina.

Thank you for those links, I'll be sure to work with those. I used one from a Dutch website that gave me information on sp. Orange and sp. Chocolate.

 

[Cowturtle]

Flipping through one of my ray books I found sketches of all the p# patterns. Now I really want to see a picture of P43.

 

[Oompa Loompa]

Wow, yes I'd love to see one of them as well!

Bump for cool thread.

does anyone know if any updates have been made to these lists?
