WASHINGTON—Scientists now calculate that Greenland sharks are Earth’s oldest living animals with backbones.
They estimate that one of those grey sharks was born in icy Arctic waters roughly 400 years ago and lived until only a couple of years ago.
Using a novel dating technique, an international team of biologists and physicists estimated the age of 28 dead female Greenland sharks.
Eight of them probably were 200 years or older.
Until now, the record holder was a bowhead whale that hit 211 years old.
