The tuatara is a reptile that is found in New Zealand which has been classed as an endangered species since 1895.
They have no ears, but have been shown to be able to hear. In 2009, Henry, a tuatara in New Zealand, become a father for the first time at the age of 111.
For some time, Henry had had a reputation for aggression and was apparently not interested in sex, but all that changed after a cancerous growth was removed from his bottom.
He mated in March 2008 with Mildred, 31 years his junior, who laid 12 eggs in June which gave birth to 11 surviving baby tuataras.
