cold because it is a reptile
Humans are affecting tuataras primarily through habitat destruction, introduction of predators such as rats and cats, and climate change. These factors threaten the survival of tuataras by reducing their available habitat, increasing predation pressure, and impacting their ability to regulate body temperature. Conservation efforts are being implemented to mitigate these impacts and ensure the long-term survival of tuataras.
Tuataras do not have four-chambered hearts; instead, they possess a heart that is more similar to that of reptiles, which typically have three chambers. However, tuataras have a unique heart structure with a partially divided ventricle that allows for some separation of oxygenated and deoxygenated blood. This adaptation is thought to improve their efficiency in oxygen use, particularly in their cool, high-altitude habitats. Overall, tuataras exhibit a blend of reptilian and more advanced heart features, but they do not possess a fully four-chambered heart like birds or mammals.
Tuataras typically dig burrows that can be around 1 to 2 meters (3 to 6.5 feet) deep. These burrows provide shelter and protection from predators and temperature extremes. The depth may vary depending on the specific environmental conditions and the individual tuatara's needs.

Tuataras mate through a process known as cloacal kissing, where the male and female press their cloacas together to transfer sperm. The female then lays eggs, which are buried in the ground to incubate and hatch. The sex of the offspring is determined by the temperature at which the eggs are incubated.

If you mean Tuataras, the native lizards, no one is certain how old they can get, but on an average around 80 years.
