The tuatara is a unique reptile native to New Zealand, often mistaken for a lizard due to its appearance. However, it belongs to a distinct order called Rhynchocephalia, which has existed for over 200 million years. Tuataras have a spiny crest along their backs and can live for more than 100 years, making them one of the longest-living reptiles. These fascinating creatures are primarily nocturnal and are known for their slow growth and low reproductive rates. Tuataras play a crucial role in their ecosystem, helping to control insect populations. They are also considered a living fossil, providing insight into the evolution of reptiles and their ancient relatives.
