Tuatara and the sun

Tuatara are endangered New Zealand animals. They belong to the reptile group because they lay eggs, have scales, have a backbone and are cold-blooded/ectotherms. Although tuatara belong to the reptile group, they are not lizards. They have some unique ancient features such as two rows of teeth in the top of the skull, a spiny egg-tooth and a third eye.  

The name Tuatara means peaks on the back or spiny back in te reo Māori. At this time, tuatara are only found in the wild on offshore islands, due to habitat loss and introduced predators.
