All type of 2 headed snakes

I have always wondered how two headed animals figure out which head is the boss? These two headed snakes can be rarely met in nature, but they are displayed in zoos and private collections. It doesn’t matter which head eats, because two headed snakes share one body. But it’s funny to see both heads being fed and it’s interesting to watch such a snake moving. Both heads can’t decide which direction is the best for the body :)
