Is tuatara is alive or dead?

The tuatara is alive. It is a unique reptile native to New Zealand, often referred to as a "living fossil" because it resembles ancient reptiles that existed millions of years ago. Tuataras are not lizards, and they are the only surviving members of the order Rhynchocephalia. Conservation efforts are ongoing to protect their populations, as they are considered vulnerable due to habitat loss and predation by introduced species.
