Grand master: Meet the shark believed to be about 512 years old


Greenland sharks grow at a rate of one centimeter a year, enabling scientists to determine their age by measuring their size.

As per a report in the Metro UK, this particular marine animal was measured at 18ft in length, meaning it could be anywhere between 272 to 512-years-old.

Mother Nature is capable of some incredible things, but we have to credit humanity with the dubious feat of aging a shark 240 years in just 16 months.

To decide the shark's age, researchers utilized a scientific model that examines the focal point and cornea of a shark's eye and connections size of the shark to its age.

For the study, the scientists analyzed the eye lenses of 28 Greenland sharks using radio technology and found out that the oldest eye lens sample was 392 years old. To improve the estimates, the researchers also assumed that the larger the shark the older it was. What makes Greenland sharks such mysterious creatures?

"And no, I don't think the shark attacked the bear, ' Nielsen wrote".

Sluggish Greenland Sharks can rarely be spotted, often choosing to live in deep waters, often as far as 400-600 meters below the water's surface.

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

If it's true, this Greenland shark will have survived through several historic moments throughout the centuries, such as the discovery of the United States and many more. "Together with colleagues in Denmark, Greenland, USA, and China, we are now 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".

Before long, Newsweek was getting in on the ancient shark frenzy, and Live Science was patiently trying to explain that, no, no known shark has been swimming around for half a millennium.

A separate study of its bones and tissues by the Arctic University of Norway may also provide clues about the effects of climate change and pollution over a long time span. "Most of the individuals in our study were genetically similar to individuals caught thousands of kilometers away".
