I don't believe the pic of the finger, but my son at 9 or 10, I don't remember(he's 45 now) got 1/3 of his index finger bitten off by a snapping turtle. He and a buddy were at the pond with their bb guns, and were messing with one about the size of the one in the pic. Bit him, and he beat it on the head with his gun getting him to release it. Just held on by a piece of skin. It was successfully reattached, so yes it can happen.I dont know about the authenticity of this photo but are you saying this doesnt happen?
