But, your family of Greenland sharks would all be living hundreds of years, too. They live 250-500 years. They are not even mature until about 150 years. So, imagine having a childhood without responsibilities of an adult for 150 years! Woot! Woot! let's play hide and seek and all the fun stuff while mom and dad handle everything lolTrue but what about when all your family of sharks die off that would be so sad![]()
