The tuatara is found in New Zealand and has a well-developed parietal eye, which is a third eye that is sensitive to light and helps regulate the tuatara's circadian rhythms. It is not snakelike in its features, and while it is often referred to as a living fossil, it is not a dinosaur but rather a reptile that is the only surviving member of its order.
