Greenland sharks live for over 270 years
Science reports on a new paper cataloging the longevity of Greenland sharks (Somniosus microcephalus). Danish scientists have used the presence of carbon 14 caused by the atom bomb testing on the 1960s to generate a growth curve and radiocarbon dating of eye lens nuclei from 28 female Greenland sharks to reveal that they have a life span of at least 272 years. It is conjectured that some individuals may be 400 years old.
