Two-headed creatures aren't just sci-fi fiction. In the natural world, double-headed animals exist. This condition is called polycephaly, a term that combines the Greek words poly- (meaning 'much') and kephali- (meaning 'head'). Although extremely rare, scientists have documented several instances of polycephaly. The two-headed animal even serves as a symbol - like the two-headed eagle, which represents grand, historical things, and was also a mark of the Byzantine Empire. This list separates myth from fact, showcasing unbelievably true examples of two-headed animals.
