i got tagged on the hand by my 9 foot female, and once by my other large female, but when she was a bit smaller, maybe 6 feet. both drew blood and looked bad, but neither really hurt... the first girl is hook trained now, once she's out of the cage she's pretty easy going. the second girl is fine once you tap her with something to break the hunting instinct.
in my experience though, sub-adults are more likely to 'head butt' you than actually bite, unless it's a feeding response.
