Two Heads Are Better Than One?

Well almost, except when those heads are attached to the same body! The condition known as polycephaly occurs when the embryo does not fully split into twins.

Polycephaly has been known to occur in mammals, birds, amphibians and reptiles. The condition is especially more prevalent with turtles and snakes. In the wild, this condition presents many survival challenges as escaping predation is often hard if not impossible. For this reason and other congenital health issues typically associated with polycephaly, these animals usually do not live long or reproduce.

An animal (or human) with this condition may have two brains but often share the same internal organs. Even feeding or deciding which direction to go can be quite a laborious task. It has to be very frustrating living like this. On the bright side, no matter how bad your day is, you are most certainly having an easier time than these two.
