Nice thread! I've been bitten by my boa constrictor, and provided pictures. I was following this thread, as I just bought a female Coastal yesterday and,,,,,, surprise!! I was bitten today.
Why no photos you ask?? Well,,, not a drop of blood, not a scratch, not a mark. I felt the teeth but I guess the yearlings don't pack a punch like the bigger ones do.
I'm planning on sticking to bites from the smaller ones. That neck bite looks a little more painful than my laugher.
