The Greenland shark has the longest known lifespan of all vertebrate species. [40] It is estimated that the species has a lifespan of at least 272 years, with the oldest individual estimated to be 392 ± 120 years of age. Estimates of age were made using radiocarbon dating of crystals within the lenses of their eyes. [9]
