The tuatara is native to New Zealand. The name "tuatara" comes from the Māori language and means "peaks on the back".
It is the sole survivor of the beak-heads which is a group of very ancient reptiles. The tuatara is the most ancient of all living reptiles and has survived for almost 200 million years. It is even older than the dinosaurs.
They range in adult length from about 40 cm (female) to 60 cm (large male).
Tuatara lack external ears, have a diapsid skull (two openings on either side). Young tuatara have a third eye (parietal eye). It is on top of the brain between the other eyes. It becomes covered over when the tuatara grows up.
Unlike all other living toothed reptiles, the tuatara's teeth are fused to the jaw bone.
The tuatara has a very slow metabolism and is a very long-lived species. It's not uncommon for an individual to live for over 100 years.
Tuatara feed on worms, beetles, sometimes bird eggs and small lizards. Due to its low metabolic rate, the tuatara eats much less frequently than other reptiles.
Tuatara are threatened by habitat loss and by formerly into New Zealand introduced predators and have been classified as an endangered species since 1895.
They were extinct on the mainland, until the first mainland release from Stephens Island into the Karori Wildlife Sanctuary - a protected natural area in Wellington - in 2005.[8]
In March 2009, a rare tuatara hatchling was found which means that the Karori Sanctuary Trust Te Māra A Tāne has successfully re-established a breeding population back on New Zealand mainland.
