Leonard Sonnenschein, president of the World Aquarium in St. Louis, holds We, a two-headed albino rat snake, Monday, Jan. 2, 2006. Sonnenschein has decided to sell the reptile, and bidding on e-Bay will start at $150,000. The 6-year-old snake came to the aquarium's attention when its previous owner distributed a circular offering it for sale days after its birth. The aquarium paid $15,000, knowing full well that most two-headed snakes don't live more than a few months. (AP Photo/James A. Finley)
