A few months ago a group of scientists managed to discover an ancient shark in the North Atlantic Ocean. Scientists estimate that this shark will be 512 years old. Researchers believe that this shark is the world’s oldest living vertebrate.
Greenland sharks can usually live for a very long time. Radiocarbon dating of the eye lens was used to determine the possible age of the shark.
Greenland sharks may live longer than scientists think. Biologists have been trying to determine the age of Greenland sharks for years.
This species of shark eats decaying polar bear carcasses. Its eyes never look healthy. Capable of living for hundreds of years, the shark does not usually stay in one place.
The reproductive system of the Greenland shark has also been very mysterious to scientists. The cold waters of the Arctic seem to be a favorite place for them to live. Scientists want to discover why Greenland sharks can live so long compared to other vertebrates.
Scientists are currently working on the entire nuclear genome sequence of this shark. Moreover, the metabolic process of this species of shark is quite different from other vertebrates.
