A hospital release says the two heads were found to have two tracheas and two esophagi, but share one heart and set of lungs. The Charlotte Observer reports state biologists believe both heads are capable of biting and distributing venom.
State herpetologist J.D. Kleopfer says in a Facebook post that two-headed snakes are extremely rare because "they just don't live that long." He says he hopes to donate the snake to a zoo.
