The longevity of Greenland sharks

 Greenland sharks are the longest -lived vertebrates on earth, with an estimated lifespan between 272 and 512 years.These Arctic sharks grow very slowly-about 1cm  per year-and do not reach sexual maturity until roughly 150 years of age,with some individuals potentially living for nearly six centuries.It is amazing these sharks can hit puberty so late.

         I am envious of Greenland sharks.
