great response Evan... thanks for confirming the jaw issue. I was a little reluctant to accept it was a chin fold, because it definitely looked skewed, not just a tissue thing. I was just worried my dude broke it when he missed the prey and slammed open mouthed into the glass! i felt so guilty for feeding him in the cage that time

I don't even know if my 'dude' is a male or female, and personally since i'm not breeding, i don't suppose it really matters and i'd rather just not have him (for the sake of applying a gender) probed. I know weights vary, but is there something comparable to a body mass index, considering age, length and weight, girth for ball pythons? He looks and acts very healthy, but wouldn't mind seeing where exactly he is in terms of size compared to others.
