This enormous Greenland shark may be the oldest living vertebrate in the world, it has been claimed.

In fact, it is estimated to be up to 512-years-old (meaning it was born before Shakespeare).

By measuring its size, they suggested the shark could have been born as early as 1505… the year Martin Luther became a monk, and King Henry VIII called off his engagement with Catherine of Aragon.

The Greenland shark lives in -1C to 10C waters and can swim as deep as 7,200ft. It is said to weigh more than a tonne.

This particular shark was measured at 18ft in length, meaning it could be anywhere between 272 to 512-years-old.

How do they know? This particular species grows at a rate of 1cm a year.

Greenland sharks have an estimated life span of 400 years, and usually spend their time swimming around looking for a mate.

Shark Found In The Wild Believed To Be 512 Years Old

It's hard to imagine anything still alive that was born in 1505. That was the year that Martin Luther became a monk and King Henry VIII called off his engagement with Catherine of Aragon... in short, a bloody long time ago.

But that's exactly what scientists believe they have found in the form of one massive Greenland shark swimming in the icy waters of the Arctic Ocean.

The shark is estimated to be up to 512 years old, which would make it the oldest living vertebrate in the world and even older than Shakespeare. And you thought turning 30 made you ancient.

Greenland sharks have been known to live for hundreds of years and spend most of their lives swimming around looking for a mate. That's a long time to wait.

They also grow at a rate of one centimetre a year, enabling scientists to determine their age by measuring their size.

This particular shark, one of 28 Greenland sharks to be analysed by the scientists, was measured at 18 feet in length and weighed over a tonne, meaning it could be anywhere between 272 and 512 years old. The shark's potential age was revealed in a study in the Science journal, according to the Sun.

If scientists have got the shark's age right, it would have been alive during major historical events like the founding of the US, the Industrial Revolution and both World Wars. Crikey.

Greenland sharks mostly eat fish but have never actually been observed hunting. Some have even been found to have reindeer and even horse remains in their stomachs. The animal is a delicacy in Norway but its flesh is poisonous if not treated properly.

Because of their longevity, academics in Norway believe that the bones and tissues of Greenland sharks may give us insight into the impact of climate change and pollution over a long period of history.

Researchers at the Arctic University of Norway are currently mapping the animal's DNA, looking at its genes to learn more about what determines life expectancy in different species, including humans.

As many of the sharks pre-date the Industrial Revolution and large-scale commercial fishing, the sharks have even been called 'living time capsules' that could help shed light on how human behaviour impacts the oceans.

"The longest living vertebrate species on the planet has formed several populations in the Atlantic Ocean," said Professor Kim Praebel at a symposium organised by the Fisheries Society of the British Isles.

"This is important to know, so we can develop appropriate conservation actions for this important species."

512-Year-Old Shark, Believed To Be Oldest Living Vertebrate, Found In North Atlantic

Researchers have found an ancient shark in the North Atlantic, believed to be 512 years old, which could be the oldest living vertebrate in the world. While the animal was discovered months ago, its potential age was revealed in a study in the journal Science.

Marine biologist Julius Nielsen found an 18-foot Greenland shark his team had been studying was at least 272 years older and possibly as old as 512 years. While the exact time of the discovery remains unknown, the news resurfaced as Neilsen completed his PhD thesis on Greenland sharks.

Earlier this year professor Kim Praebel, from the Arctic University of Norway, found that Greenland sharks could have a lifespan of up to 400 years. But the recent research proves that the species could live to be even older. With the help of a mathematical model analyzing the lens and the cornea that linked size with age, researchers found a way to predict age. The method to discover the age of the animal was determined last year.

By measuring the size of the recent Greenland shark found, researchers suggest the animal could have been born as early as 1505, making it even older than Shakespeare. Greenland sharks — also known as the gurry sharks, or grey sharks, are large sharks of the family Somniosidae — grow at a rate of one centimeter a year, enabling scientists to determine their age by measuring their size.

The shark that was found to be 512 years old was one of 28 Greenland sharks to be analyzed by the scientists.

"It definitely tells us that this creature is extraordinary and it should be considered among the absolute oldest animals in the world," Nielsen said last year.

Steven Campana, a shark expert from the University of Iceland, said last year: "Fish biologists have tried to determine the age and longevity of Greenland sharks for decades, but without success. Given that this shark is the apex predator (king of the food chain) in Arctic waters, it is almost unbelievable that we didn’t know whether the shark lives for 20 years, or for 1,000 years."

Greenland sharks are found in deep water in the Atlantic Ocean, from Canada to Norway. The species is often plagued by worm-like parasites that latch on to their eyes. These sharks have been known to feast on rotting polar bear carcass.

In September, Nielsen shared a stomach-churning photo of the remains of a polar bear extracted from the stomach of a Greenland shark.

"And no, I don’t think the shark attacked the bear," Nielsen wrote. "It is much more likely a carcass found by the shark. Polar bear remnants in Greenland shark stomachs are extremely rare and polar bears are considered of no importance as food source for sharks in Greenland waters."

Praebel had been looking into how Greenland sharks' "long life" genes could shed light on what determines life expectancy in different species, including humans.

"This is the longest living vertebrate on the planet," he said. "Together with colleagues in Denmark, Greenland, USA, and China, we are currently sequencing its whole nuclear genome which will help us discover why the Greenland shark not only lives longer than other shark species but other vertebrates."

Amid the study into "long-life" genes, studies have also shed new light on the shark's behavior.

"Since the Greenland shark lives for hundreds of years, they also have enough time to migrate over long distances and our genetic results showed exactly that," Praebel reportedly said. "Most of the individuals in our study were genetically similar to individuals caught thousands of kilometers away."
