The tuatara is a fascinating and unique creature found only in New Zealand. One of its most distinctive features is its third eye, which is located on the top of its head and is used to regulate its body temperature. Tuatara are the only reptiles that still have this third eye, which is why they are sometimes called “the living fossils”. Other notable features of the tuatara include their sharp beak-like mouths and long tongues, which they use to catch prey. Their scaly skin is also covered in horny spikes, giving them a very spiky appearance!
