For most of us, the future inevitably means getting old and swapping our health for wrinkles.

But some creatures on Earth can resist aging to an unbelievable extent, and some even escape it entirely.

We can learn a lot from Earth's oldest life forms, as they could hold the secrets to immortality.

So, from 500-year-old sharks to resurrected million-year-old

anomalies, let's explore some creatures that reveal the secrets of immortality.

You're listening. You're listening. You're be amazed.

Often described as a living fossil, the Tuatara can only be found on the offshore island of New Zealand.

Its nickname isn't just a mean joke.

Tuatara as well and truly earned their description as fossils as they're thought to be capable of living up to 200 years.

Having grown the Earth since as far back as 225 million years ago, the Tuataras of today have changed little since the last T-Rex kicked the bucket.

Their survival and longevity are in part due to their hearty nature, being able to

survive in a wider range of temperatures than most other lizard species. On top of this, they have

exceptionally slow metabolisms, and they seem to prefer a leisurely pace of life. It can take them up to

40 years to reach full size, usually around 2.5 feet, and they don't even reach sexual maturity until they're around 20.

But despite being late bloomer's evidence suggests they're constantly, shall we say, virile, right until the end of their lives.

Atuatar and captivity called Henry highlighted the amorous

capabilities of his species when he became a father at the ripe old age of 111. This was after

almost 40 years of showing no interest in females. So remember fellas, it's never too late.

Just channel your inner Henry the Tuatara.

Next up, sitting at the top of the pile of the oldest terrestrial animals on earth is the

Aldabra giant tortoise, bound on the islands of the Aldabra Aetal in the Indian Ocean.
