HOLY CRAP!!!! I've seen the Synodontis "Upside Down Cat, I've even eaten (and thoroughly enjoyed) Pineapple Upside Down Cake, but I've only heard rumors about the mysterious Potamotrygon species "Upside Down Ray".
And all these years I thought they were a myth. One less mystery in the world of cryptozoology.
Now where is my Bigfoot smiley icon?
Just kidding, great accomplishment and thanks for sharing.
