They can even swallow or eat their selves when they too much stress or hungry.  Snakes are cold blooded & if they get too hot they become confused & disoriented, they also get a ramped-up metabolism causing them to have a false sense of hunger & desire to eat the first thing they see and never use their brain, like what happened in this video below. Snake may also attack themselves if they shedding and have poor eyesight can be mistaken their tail as prey.
