This California King Snake amazingly has two rare disorders: it's albino and has two heads. That combination only comes about every 50 years. Surprisingly though, the two-headedism (or polycephaly) of the snake is actually more common than albinism.
Each head takes on a different personality, one is more agressive and seems to control the movement of the body, while the other is more passive. They can usually get along with one another (what choice do they have?) but once feeding time hits all hell breaks lose. Their heads have to be 'separated' with a divider because they will fight each other for food (even though it's going down the same body). The snake is on display in a zoo in Ukraine.
