Axanthic Burmese Python?

I've never seen a burm that is BLACK like this! Anyone have an idea of what kind this is? The Description says its a granite, but i've never seen a granite like that...

IDK, but it looks very cool.

1st off it would not be considered a axanthic. As axanthics are not black like that they are grey. It would be called a IMG (increase melanism gene). By the way it looks like a normal granite in some bad lighting.

Imo it doesnt look like a granite. If you look down the sides it lightens up with normal looking markings. You cant really see it that well with that video though. Very interesting animal.
