Like how can they even fucking know that at this point? Has humanity tracked a single one for that long yet?
Longevity
The Greenland shark has the longest known lifespan of all vertebrate species.[19] One Greenland shark was tagged off Greenland in 1936 and recaptured in 1952. Its measurements suggest that Greenland sharks grow at a rate of 0.51 cm (0.20.4 in) per year.[20] In 2016, a study based on 28 specimens that ranged from 81 to 502 cm (2.716.5 ft) in length determined by radiocarbon dating that the oldest of the animals that they sampled, which also was the largest, had lived for 392 ± 120 years (a minimum of 272 years and a maximum of 512 years). The authors further concluded that the species reaches sexual maturity at about 150 years of age.[19][21]
