Tuatara: Aotearoa's Living Fossils
Everyone seems to know about the tuatara, Aotearoa’s most well-known reptile. Their Māori name means peaks on the back and refers to their little white spines.
Tuatara are born with some funky features, including a spiny egg tooth which helps them break through their shell, and even a third eye which covers over when they are born.
Tuatara lay their eggs in burrows and cover them over with dirt. These eggs then incubate for 13-14 months before the baby tuatara hatch. The gender of tuatara hatchlings is controlled by temperature. Eggs in colder temperatures produce more females, and eggs in warmer temperatures produce more males. Unfortunately, this means that along with predation and habitat destruction, tuatara populations will change with a warming climate. They are already extinct on the mainland.

Tuatara can live for over 100 years, but what is even cooler is that their ancestors are from the age of the dinosaurs, 200 million years ago! Tuatara are known as living fossils. What are fossils? Learn more HERE.
