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 head with eyelashes is female and the head with a moustache is male. 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.
