10 Animals That Can Live for Over 100 Years

5. The Resilient Reptiles: Tuatara

The tuatara, a reptile native to New Zealand, is often referred to as a living fossil, having remained largely unchanged for over 200 million years. These ancient creatures can live for more than a century, with some individuals reaching over 110 years of age. Tuataras are unique in the reptile world, possessing a third “parietal” eye on the top of their heads, which is believed to be involved in regulating their circadian rhythms and hormone production. Tuatara’s longevity is supported by their slow metabolism and low reproductive rate, with females laying eggs only once every four years. They thrive in cool climates, with their slow growth and development allowing them to conserve energy over long periods. However, tuataras face significant threats from habitat destruction and introduced predators such as rats and stoats. Conservation efforts are crucial to ensuring their survival, with breeding programs and habitat restoration playing key roles in preserving these remarkable reptiles. The tuatara’s story is one of ancient resilience, a reminder of the enduring power of evolution.
