The Tuatara!
Tuatara
One of only 2 native reptile species in New Zealand, the Tuatara resembles iguana type lizards, but is actually closer to living fossils such as sharks and crocodilian species.
This highly endangered species graces the New Zealand 5 cent piece, and is one of the most unique creatures you're likely to come across!
The temperature that the eggs are incubated at completely affects the gender of the hatchilings! The males can reproduce yearly, but the females only every four years. If the eggs are incubated at 18 deg(Celsius) they will all be female, 20 deg 80% likely to be female, 21 deg 50/50 whether male/female and 22 degrees 80% likely to be male!
