OK, ALOT of people here seems to be a newb on stingrays.
So, I gathered some info which I hope will help with your identification of commonly found rays.
Let me start by saying, none of these photos nor the fish in the photos belong to me.
Now, let's begin.
Potamotrygon reticulata:
These are often sold as, "teacup" rays. Extremely variable in color and pattern. But one thing you can't miss is the flattened tail, which is outlined with a light colored skin on the sides. They usually sport a labyrinth or ornate pattern on the disc, resembling that of a net.
Potamotrygon humerosa:
These are also commonly sold as, "teacup" rays. They have circular patterns (but not spots) on the disc with sand paper like disc when felt. They are very often confused with the Potamotrygon orbignyi, which has a smooth disc to the touch.
Potamotrygon orbignyi:
These are almost indistinguishable from the humerosa, except it has a smooth skinned disc as oppose to the P. humerosa's rough sand paper like skin.
Potamotrygon yepezi:
Although the identity of the "true" P. yepezi is still not confirmed, this ray pictured below is commonly sold as the P. yepezi. These has random marks on the disc, which does not define any spots or ornate patterns.
Potamotrygon hystrix:
These are easy to disguish due to the moltted like pattern on the disc with small scattered dots within those patterns:
I think that's about it. These are very very basic descriptions and would definitely need further development, but I'm just too lazy.
Feel free to correct or add any content.
