Record holder for life expectancy among marine and land vertebrates – a Greenland shark 5.4 meters long. Julius Nielsen – University of Copenhagen biologist specified for journalists that he has been studying this shark for several years, however previously they believed that she was two hundred to three hundred years old. However, having caught this giant sea animal the other day and measured it age with modern research (radiocarbon analysis the lens nucleus of the eye that was made in the Arctic University of Norway), scientists were in shock – a shark for 500 s odd years.

Greenland sharks are very slow predators as they live in the cold waters of the North Atlantic and the Arctic oceans, people are practically not attacked (only a few are noticed case when these predators scared with their aggressive behavior divers and fishermen), grow very “sluggish”, reaching puberty at the age of 150 years. Being caught don’t resist like other sharks, so studying them is very easy.
Scientists have called them “time capsules,” the study of which may bring oceanologists closer to the solution of many secrets of the ocean and the degree of impact on its inhabitants of human activity.
