It is considered extinct in the wild - but Dublin Zoo is celebrating the birth of a male scimitar-horned oryx.
Born in early December, the newest addition brings the total herd at the zoo to four.
The scimitar-horned oryx was once widespread across northern Africa but due to overhunting and habitat loss, they have gradually disappeared from the wild.
The species has been classified as extinct in the wild by the International Union for Conservation of Nature.
Since 2013, Dublin Zoo has supported the reintroduction programme for the scimitar-horned oryx in Tunisia.
Through conservation programmes, zoo-bred oryx have been reintroduced into semi-wild areas.
Zoo team leader Helen Clarke-Bennet said: "We are absolutely thrilled with the new arrival and recognise the significance of this birth in the conservation of the scimitar-horned oryx.
"The calf has shown strong signs of settling into its new surroundings and is mixing extremely well with the rest of the herd."
