NUUK - Scientists have discovered ancient sharks that can live up to 600 years. Earlier this year, professor Kim Praebel, from Arctic University of Norway found that Greenland sharks were able to reach 400 years of age.
In the development of the research it was revealed that the species could even become older. The 4.8-meter long female shark examined by marine biologist Julius Nielsen and her team was at least 272 years old, possibly even up to 512 years.
By utilizing research published nine years ago, scientists observed lens crystals, a type of protein that is also present in the human eye. The crystal contains carbon, including a number of radioactive carbon-14 isotopes, and unlike other proteins, it remains stable throughout the life of the animal.

However, because it is difficult to determine the background of carbon-14 levels in the ocean, and because Nielsen and his colleagues do not know the location of the shark was born, it is not yet right. Even so, he sets Greenland sharks as vertebrates with the longest lifespan on Earth and the research can be proven theoretically, the largest can be almost six centuries old.
Earlier this year, Professor Praebel researched how the animal's "longevity" gene could explain the factors that determine life expectancy in other species, including humans.

"Together with colleagues in Denmark, Greenland, the United States and China, we are currently sequencing the entire nuclear genome. It will help us to find out why Greenland sharks not only live longer than other shark species, but also other vertebrates," said Professor Praebel, quoted from Mirror.co.uk, Thursday (12/14/2017).

He said that the shark was a "living capsule" which could help explain the impact of humans on the ocean so far. Sharks' tissues, bones and DNA can also provide clues about the effects of climate change and pollution over a long period of time.
