An aquarium in Ireland has welcomed what is believed to be one of the world's only lesbian penguin couples, after keepers observed two females exhibiting courting behaviour.
Missy and Penelope, who are six and seven years old respectively, were thought to be Ireland's first ever same-sex penguin couple.
They were among five couples who have paired off for the breeding season at Dingle Oceanworld in Kerry, according to reports in the Irish Examiner.
Other gay penguin couples have achieved worldwide fame, including Roy and Silo in New York's Central Park Zoo and a King penguin pair who became adoptive fathers of a chick from an abandoned egg.
Dingle Oceanworld's head penguin keeper Kate Hall said that while male same-sex couples are not unheard, it is rare for two female penguins to pair off.
