Aquarium’s 2-Headed Snake Dies At 8
More than 1 million people have seen “We” over the years. Children were especially fascinated by the snake, wondering how two heads could coexist on the same body.
“We” sometimes strained to slither in two directions at once.
Born with both male and female genitalia, “We” was bought from a snake breeder in Indiana for $15,000 when the reptile was just a few weeks old.
A taxidermist is preserving the snake’s body, which should be back on display within a week.
