This snake was discovered in China in 2009 with a single clawed foot growing out from its body. The 16 inches long mutant reptile was found by Duan Qiongxiu clinging to the wall of her bedroom in suining with its talons. Mrs. Duan was so scared that has beat the snake to death with her shoe. Growing a foot is a very rare mutation for a snake they more frequently grow two heads and scientists are working to find out if the foot evolved from changes in the snake's environment.
