His dad named it Mary-Kate and Ashley, after the teenage TV and movie stars, the Olsen twins, and thinks it might have a future in show business. Two-headed snakes are not as rare as you might think. They have been found in the United States, Argentina, Honduras, Sri Lanka and Spain. Gordon Burghardt, zoologist at the University of Tennessee, has studied several two- h e a d ed snakes. And every time the heads were so independent they even fought for food! 'You can have these fights go on for hours,' he says. Sometimes the heads become so aggressive they can even try to eat each other! Two-headed snakes also have a great deal of difficulty deciding which direction to go. That's probably because one head wants to turn left and the other one wants to turn right.

Last autumn, a ten-year-old American boy from Kentucky tried to pick up a snake with a stick and then noticed that it had two heads. Imagine how surprised he was when the snake grabbed the stick with both heads! His dad named it Mary-Kate and Ashley, after the teenage TV and movie stars, the Olsen twins, and thinks it might have a future in show business. Two-headed snakes are not as rare as you might think. They have been found in the United States, Argentina, Honduras, Sri Lanka and Spain. Gordon Burghardt, zoologist at the University of Tennessee, has studied several two- h e a d ed snakes. And every time the heads were so independent they even fought for food! 'You can have these fights go on for hours,' he says. Sometimes the heads become so aggressive they can even try to eat each other! Two-headed snakes also have a great deal of difficulty deciding which direction to go. That's probably because one head wants to turn left and the other one wants to turn right.
A lack of understanding between two heads can lead to even greater difficulties: a predator would quickly swallow the hesitant snake! 'So their chances of surviving in the wild are nil,' says Burghardt. 'They can be easily attacked by predators. Two heads are NOT always better than one'. Even in captivity, there are problems. Food should be given to one head first and a moment later to the other one. If both mouths are busy chewing, they won't attack each other. On the whole, though, they can do quite well in captivity, says Burghardt. Thelma and Louise, a two-headed snake at the San Diego Zoo had 15 normal babies. She was 17 years old when she died Not long ago, a two-headed boa constrictor was born in New York. Experts don't know why she was born this way. Indy the snake has has 26 brothers and sisters but because she's one of a kind, she could one day be sold for about $500,000 to a zoo or a collector. Right now Indy's second head can't eat. drink or breathe but it flicks its tongue and looks around. The two- h e a d e d monsters of myth may have a basis in reality.
