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.
This
two headed albino milk snake was born two years ago in Florida.
The condition
is known as Polycephaly and occurs when monozygotic twins fail to separate
completely. Most organisms with this condition will not live for long, but
occasionally you will get cases like this one, where the snake(s?) seem healthy
enough and can live for years.
The
heads act independently of one another, and will fight over food given the
opportunity.
