Leonard Sonnenschein, president of the World Aquarium in St. Louis, holds a two-headed albino rat snake. The eight-year-old oddity of nature was known affectionately by fans worldwide as "We" died of natural causes in 2007.
Oct. 28, 2011 photo provided by Daniel Parker of Sunshineserpents.com, a two-headed albino Honduran milk snake is shown in Ridge Manor, Fla. Parker, a University of Central Florida biologist, says that most two-headed snakes have typical coloration. Albino snakes don't have dark pigmentation in their skin. Albino milk snakes appear in bright shades of red, orange and white. The biologist says two-headed snakes have been documented to live as long as 20 years in captivity. But with two brains giving commands to a single body, Parker says the snake would have a difficult time surviving in the wild. (AP Photo/Sunshineserpents.com, Daniel Parker)
