New Zealand - Fauna: Tuatara. The Tuatara are endemic to New Zealand and one of their natural icons. They grow very slowly, live to over 100 years old and are the only survivors of an ancient group of reptiles which roamed the earth, along with the dinosaurs, over 200 million years ago...which makes them the world&#x27;s oldest living reptile. Tuatara are an endangered species; this one was photographed at Nga Manu Reserve near Waikanae by Sid Mosdell,
