Scientists Learn That This Shark Is Earth’s Oldest Creature With A Backbone
The Greenland shark is a fascinating sea creature. Known as the longest-living vertebrae, this species of shark can live to be 400 years old. This large shark is also known by other names, such as a gurry shark or a grey shark. It lives in the deep depths of the frigid Artic Ocean and it has only been since recently that scientists have learned something solid about it. You have to check out the footage below to see this shark in its natural habitat.
The Greenland shark’s long life is because of the slow pace that its body grows. At a rate of about a centimeter a year, this shark owes its long life to the same mechanism as a tortoise.
Scientists once believe that the Greenland shark’s lifespan was about 272 years. However, this conclusion has been turned upside down as the researchers discovered two members of the species who were estimated to be more than 350 years old.
This species of shark is a reminder of how much we do not know about the vast ocean. What will science discover next?
