A tuatara typically stays in its egg for about 11 to 16 months before hatching. The exact duration can vary depending on environmental conditions such as temperature. This long incubation period is one of the reasons tuataras have a slow reproductive rate. After hatching, the young tuataras are independent and start their lives on land.
