Like you stated, been bit at least a dozen times by baby boas and balls on the hands and fingers. I had a female Dumerils bite my forearm when changing her water. Also another on the forearm by a Peruvian boa, he liked to bite when you least expected and loved to strike the glass when you walked by on occasion. And once I got tagged on the ribs by my Surinam boa. The worst part was he never ever bit, not even as a baby. And when he did I had on a white shirt and a bunch of people over. It was not pretty, nor a good way to win over non snake people, lol. The three bites were all from adults too. I think it kinda comes with the territory of being a snake keeper.
