Residents of a village in Bali got a shock when they spotted a two-headed snake in their midst -- a rare find in the wild.The reptile was seen slithering in the central part of the Indonesian holiday island last week."When I got home from work, I parked my motorbike next to the snake," said local resident Gusti Bagus Eka Budaya."I looked more closely and it turned out to have two heads. I was shocked."A video shows several children gathered around the tiny serpent - small enough to fit in the palm of a human hand - as it slides about a banana leaf decorated with a traditional Balinese Hindu offering.It was not clear what kind of snake it was or whether it was venomous.Experts have previously been quoted as saying that two-headed snakes rarely occur in the wild and have usually been bred in captivity.
