I've been doing research for a class recently on the use of UV reflective scales/feathers for communication by various animals, but haven't been able to find much on snakes. A lot of birds, fish, and butterflies reflect UV light as a means of communication and mate selection, but the only reptile I can find with unique scales are Gabon vipers. Apparently the 'black' in their pattern creates an enhanced "shadow" effect by absorbing more uv radiation than the rest of their scales.
However, I have also seen posts where people look at their all white pythons, and some show faint pattern under black light. Just wondering if anyone has found a particular morph (or individual) that is particularly reflective.
