dc.description.abstract Greenland shark (Somniosus microcephalus), a species iconic to the Arctic Seas, grows slowly and reach >500 cm total length suggesting a lifespan well beyond those of other vertebrates. Radiocarbon dating of eye lens nuclei from 28 female Greenland shark (81-502 cm in total length) revealed a lifespan of at least 272 years. Only the smallest sharks (≤ 220 cm) showed sign of the radiocarbon bomb pulse, a time marker of the early 1960s. Age ranges of pre-bomb sharks (reported as mid-point ± 1/2 range at 95.4 % probability) revealed the age at sexual maturity to be at least 156 ± 22 years, and the largest animal (502 cm) to be 392 ± 120 years old. Our results show that Greenland shark is the longest-lived vertebrates known and raise concerns for species conservation.
