The two-headed monsters of myth, as a matter of fact, have a basis in reality. Two-headed snakes are very rare odd creatures but not unheard of, and one two headed snake recently found in zoo in southern Ukrainen .
"Polycephaly is a condition of having more than one head. The term is derived from the stems poly- meaning 'many' and kephal- meaning "head", and encompasses bicephaly and dicephaly (both referring to two-headedness). A variation is an animal born with two faces on a single head, a condition known as diprosopus. In medical terms these are all congenital cephalic disorders.” - Wikipedia
A two-headed snake has gone on display at a zoo in southern Ukraine.
The "Skazka" (Fairy tale) zoo in the Crimean city of Yalta on the Black Sea said Wednesday that the albino California Kingsnake has two heads that think, react and eat separately, though one is more passive than the other.
Dmytro Tkachov, a zoo worker taking care of the snake, said he puts a barrier between the heads when feeding the snake lest one eats the other.
The snake will be on display at the zoo until mid-September.
