long "line" on my ball belly

[muddoc]

That could be it, but as he said it has been there a while. I wouldn't have noticed something like this either, kind of like how I never really noticed my snake's "belly button". This had to have been something from when it hatched or rubbing on something very sharp like a piece of cypress mulch or a sharp log or stick.

Actually if you reread the OP, he says he didn't notice it when he got it.
