HISTORY QUIZ
​

Two-headed snakes have been found in the United States. Gordon Burghardt, zoologist at the University of Tennessee, has studied several two- h e a d ed snakes and he says that sometimes the heads become so aggressive and even try to eat each other! A lack of understanding between two heads can lead to even greater difficulties: a predator would quickly swallow the hesitant snake. 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. Thelma and Louise, a two-headed snake at the San Diego Zoo had 15 normal babies. Indy the snake 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. The two- h e a d e d monsters of myth may have a basis in reality.
