Been bit 2 times in 13 years. one from a 6ft Black rat which was more liek a pinch. And the other from my 7ft+ Female boa. Wasn't the boas fault cause lil step nephew was jumping in her face and wouldn't listen, so the boa struck at his face but i put arm there and took every tooth he had in my arm.

Large boa bites are NO FUN. It burned for a hour after and wouldnt stop bleeding for 2 hours after.
