Well there HAVE been reports of anacondas swallowing children although nobody can seem to confirm that. From my own studies I have found that the consensus is that a large python or anaconda COULD swallow a human adult if the adult was actually "cooperative". There have been cases where an anaconda TRIED to swallow a human but the person was able to fight it off and apparently the anaconda didn't think it was worth the effort. So I guess the real answer is a large python or anaconda CAN get you down if you are willing to let it. Anybody out there want to prove that?
