The unique reptile endemic to New Zealand is the sole survivor of an ancient species that once walked the earth with dinosaurs.
About 130 years ago – as New Zealand women celebrated their world-first right to vote, athletes competed in the first international Olympic Games, and the first motion pictures were flickering into view – a tiny mottled green reptile with a spiny back was hatching on a small New Zealand island.
The baby tuatara – a unique and rare reptile endemic to New Zealand – emerged from his burrow into the forest floor, where he miraculously evaded birds, rats and cannibalistic adult tuatara to reach his full adult size – nearly one kilo in weight and half a metre in length – by the time he was 35.
Over the next few decades, he fossicked about Stephens Island at the northern tip of the South Island, hunting by night and sunning himself by day. Then, at roughly 80 years old, his time in the wild ended. In 1970, he was transported to a museum in Invercargill, the country’s southern-most city, to begin a new life in the public eye as ‘Henry the tuatara’.
Now believed to be between 110 and 130 years old, Henry is likely the world’s oldest living tuatara and New Zealand’s oldest resident. He is also the most famous and beloved of his species.
New Zealand has no native land-based snakes or turtles, and the majority of its 150 or so reptiles are lizards. But while the tuatara – New Zealand’s largest reptile – may look like a lizard, it is not one. Rather, it is the sole survivor of the ancient reptile order Sphenodontia, which walked the Earth with dinosaurs 225m years ago.
They are considered a taonga (treasured) species for Māori and hold a special place in the hearts of New Zealanders, appearing on coins, stamps, and in children’s books and cartoons.
The reptiles have also long fascinated scientists – they have a parietal or “third” eye on the top of their head which detects light. They are one of the slowest growing reptiles in the world, while boasting the fastest swimming sperm of any reptiles studied to date.
They can take 16 months to hatch, reproduce past the age of 100 and live up to 200 years, making them one of the longest-living creatures. Once widespread across New Zealand, tuatara now survive primarily on a scattering of offshore islands where introduced predators have been eliminated.
Some, such as Henry, live in state-of-the-art digs, where their environment, diet and health is closely monitored.
The ancient reptile’s skin is the colours of a dappled forest floor. From the top of his wide strong head to the tip of his tail runs a line of pearly spikes. His big black eyes are as glossy as obsidian and, with his head poised high, he looks as royal as his monarch namesake, Henry VIII.
Henry grants his visitors a brief audience, and with the late-afternoon sun slipping behind the trees and the air cooling, he decides it is time to return to his warm burrow.
Henry has not always been so amenable – for 17 years, he was so irascible he had to be completely isolated from other tuatara. Sex, meanwhile, was of little interest to him – when handlers tried to mate him with Mildred 40 years ago, he twice bit off her tail.
In 2007, the removal of a cancerous tumour on his genitals changed all that – including his personality and his libido – and the following year, Henry made international headlines when he became a first-time father, aged 111.
During his long life, Henry has clocked up a list of headline-grabbing experiences, including meeting Prince Harry in 2015, starring in an award-winning documentary and holding the world record for living in captivity for over 46 years.
