In the frigid waters of the sub-Arctic ocean lurks a mysterious and slow-moving beast known as the Greenland shark. It’s a massive animal that can grow up to 20 feet in length. Now, new research suggests it may have a massive lifespan as well.
According to a paper published Thursday in Science, the Greenland shark could live for well over 250 years, making it the longest-living known vertebrate on Earth.
“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.”
