Hermaphlamingo

Hermaphlamingos are an alien species from Vergon 6. The planet was about to implode so Fry, Leela and Bender saved a pair of Hermaphlamingos among other Vergonian creatures. They had to save two of each kind but Hermaphlamingos have two heads in one body, the right head is female and the left head is male since it has a moustache. It may now be extinct because the planet imploded and Nibbler ate the ones saved.

Trivia

 * They're called Hermaphlamingos because a species with both male and female gonads is called hermaphrodite.
