[00:00.00]It's home to a living fossil, [00:02.09]a relict, [00:03.42]barely changed for over 100 million years. The tuatara. [00:07.91]And half the world's population survive on this one island refuge. [00:12.89]During the reign of the dinosaurs, [00:14.42]the ancestors of the tuatara were everywhere. [00:17.62]They survived the cataclysm that killed off the dinosaurs, [00:21.07]but then couldn't compete with the mammals and died out. [00:24.95]Everywhere, except on what was then a mammal-free New Zealand. [00:29.28]Unlike mammals, [00:30.63]tuatara live life in the slow lane. [00:34.68]Days can pass when they barely move a muscle. [00:37.99]Sometimes taking just one breath an hour. [00:41.49]They feed on wetas, [00:43.25]beetles and other invertebrates [00:45.60]but don't appear very good at catching them. [00:48.30]Even after millions of years of practice, [00:50.65]eye-mouth co-ordination is not what it could be. [00:53.86]"Survival of the fittest" just doesn't seem to apply here. “ [00:58.49]The tuatara's survival, [01:00.15]first on New Zealand, [01:01.33]now on Stephens Island, [01:02.75]proves a point - islands are pretty safe places to be, [01:06.81]at least until invaded.
