Night comes cool and salty to the little island, and that is exactly how the old one likes it.
Most reptiles love the heat. The old one is a tuatara, and tuatara are different. They come out when the air turns chilly and the fog rolls in off the sea, at temperatures that would send a lizard hurrying home to bed.
The old one stepped out of his burrow, slow and certain, spines standing along his back like a row of little mountains. That is what his name means. Tuatara, in the Maori language: peaks on the back.
He had lived on this island off the coast of New Zealand for more than a hundred years.
He shared his burrow with a small grey seabird called a fairy prion. She fished at sea all day. He hunted all night. They passed each other at the door like polite neighbors, and it worked splendidly.
Tonight he crunched a beetle. He stalked a weta, a big flightless cricket, and won. The stars turned slowly overhead. He did everything slowly. Slow breath. Slow heart. Slow, wonderful life.
Then, near dawn, he found the strange thing.
A tiny tuatara was sitting at the mouth of his burrow.
It was new. Brand new. It had slept in its egg under the soil for about a year, growing, waiting, and had finally dug its way up into the world.
"Hello," said the little one. "What are you?"
"The same thing you are," said the old one. "Look closer."
The little one looked. Same peaked back. Same steady eyes. And on top of the little one's head sat a tiny pale patch, like a freckle of moonlight.
"You have a third eye," said the old one. "On top of your head. It drinks the light of the sky, and it helps you know day from night, season from season. I have one too. Mine is covered by scales now. Old eyes get blankets."
"Are there many of us?" asked the little one.
The old one was quiet for a moment.
"We are the last of a very old family," he said. "Our relatives lived alongside the dinosaurs, more than two hundred million years ago. You can meet them today only in stone. But we are still here. We were here before, and we are here after, and that is a kind of magic almost nothing else on Earth can claim."
"Because we are fast?"
"Because we are slow," said the old one. "The hurrying world runs past. We stay. We take a hundred years and use every single one of them."
The sky was turning pearl grey. The fairy prion swooped home from the sea, folded her wings, and squeezed past them into the burrow with a sleepy squawk.
"Morning shift," said the old one. "Come. I will show you the best cool shadows on the island."
They walked into the fog together, one very new and one very old, the newest member of the most ancient family and its keeper.
Slow is not the same as stopped.
Ask the mountains. Ask the tuatara.
