• Question: does a two-headded snake have one brain and is all one or does it have two brains and act as two different animals?

      A puzzling question – because it’s something thats so rare, what we’ve seen can vary, some two headed snakes have had two heads with two brains that both functioned, some had two heads with one brain etc. It has been noted that some two headed animals seem to ‘argue’ with one head trying to get the body to do one thing and the other thinking differently! Some two headed snakes have even tried to eat the other! It really depends then on if the two heads have two functioning brains or not.

      I cannot imagine a two headed snake would survive long and would most likely be two snakes fused during the embryonic stage so i think it would have two brains
