I've only been bitten once by an adult BP (she was 1,900 grams of fury back then) but I was prepared due to her situation and was wearing gloves at the time. She still managed to get a couple of teeth through the gloves though.

The hatchlings/babies are another matter. I've got one that tried to bite me when she was barely out of her egg and still to this day will nail me if she can manage it LOL. She's just a treat that girl! I always seem to laugh when the little bp's take a swing at me. So small and yet so determined to bite the hand that feeds them. It's sort of cute really.
