The number of gay penguins at the Dingle Oceanworld Aquarium in Kerry has quadrupled since Ireland legalized same-sex marriage.

The aquarium has confirmed that out of the 14 Gentoo penguins there, eight are cohabiting with another penguin of the same sex.

"In New York City zoo a gay penguin couple reared a chick and that made international headlines because they were seen as the only gay penguin couple in the world and yet we have four couples here in our place.
