The newest enclosure in Dublin Zoo opened today.
It's called the Nocturnal House - and its first residents are already in situ.
The Aye-Aye lemur, the first of its kind in Ireland, officially moved in this morning.
The endangered primate comes from Madagascar in Africa and is a distant relative to humans.
It has an elongated middle finger to help find food and sleeps during the day.
The new house will be pitch black and lit by a red light for visitors as the animals' body clock is the opposite to ours.
Director of Dublin Zoo, Dr Christoph Schwitzer, is delighted with the new animals:
"I'm a great fan of lemurs, I really love lemurs".
"They [Aye-Ayes] are just lovely lovely creatures and I'm really glad we have them here in Dublin Zoo".
Fun fact also - Maurice from the movie Madagascar is an aye-aye.
