any ID on these rays?

Hey everyone,
I was checking out aquascape and I saw these rays labeled as "spotted rays" but I havent heard of them before. Are they just a hybrid or something or can someone figure out what they are?
Here is a link:

The pictures resemble the pictures I have seen of the Blue Mantilla Stingrays. I could be mistaken though, perhaps someone else will know better than I do.
