“I am 95% certain that the oldest of these sharks is between 272 and 512 years old,” said lead author Julius Nielsen, a marine biologist at the University of Copenhagen.
“That’s a big range, but even the age estimate of at least 272 years makes it the oldest vertebrate animal in the world.” The oldest animal record holder is a clam called Ming that was dredged up from the ocean floor off the coast of Iceland.
Greenland sharks are among the largest sharks on the planet.
They are dark brown or purple with small, beady eyes.
Still, if Nielsen’s estimations are correct, the Greenland shark would be a record breaker.“They are basically a giant swimming nose,” said Aaron Fisk, a professor at the University of Windsor who has studied the Greenland shark for two decades.
