• Corn snakes are naturally timid, like most snakes their primary defence is flight (running away not flying - well, slithering away not running). If they can't get away and they are scared, they will vibrate their tail against something to make a noise. If you really really try hard to piss them off you might get a nip but it's never happened to me or my kids, and they don't have much in the way of teeth anyway.
