When he was threatened by something big, what did he do?
Slither thither.
I don't know. The one occasion I can remember him being threatened by something larger, I was (unwittingly) doing the threatening, insofar as I forgot the principle of do-not-handle-after-a-recent-feeding - he actually struck at me, the one and only time he ever did so. Which was quite a surprise, as they're normally quite docile, as long as you remember to, you know, not handle them after a feeding....
