The largest great white shark ever recorded, nicknamed âDeep Blueâ, weighed over 2 tonnes and measured around 20 feet from head to tail. While sleeper sharks (the Greenland shark and its cousins the Pacific sleeper and the southern sleeper) can live for hundreds of years, the methodology used to age this particular type of shark requires that the shark be, well, dead.Since sharks are cartilaginous, researchers used eye lenses (the only truly âhardâ part of the shark) for radio carbon dating. The shark is estimated to be up to 512 years old, which would make it the oldest living vertebrate in the planet and even older than Shakespeare. Marine biologist here! So we can isolate the tissue that formed when the shark was a pup, and do radiocarbon dating." Its measurements suggest that Greenland sharks grow at a rate of 0.5â1 cm (0.2â0.4 in) per year. According to the journal Science, Greenland sharks grow at just one cm a year. Described as the 'least shark-like shark', it is thought to have risen from within a group of fish known as acanthodians or spiny sharks. The shark would have been alive during major world events such as the founding of the US (1776), the arrival of the First Fleet at Botany Bay, NSW (1788), both World Wars (1914-1918 and â¦ Nielsen says there is some uncertainty around that estimate. So when they discovered a female shark measuring a whopping 18 feet, they knew this creature had to be incredibly old. And you thought turning 30 made you ancient. The Greenland shark has the longest known lifespan of all vertebrate species. It was the oldest of a group of 28 Greenland sharks studied. Oldest shark teeth The earliest shark-like teeth we have come from an Early Devonian (410-million-year-old) fossil belonging to an ancient fish called Doliodus problematicus . Stunning footage of what may be the world's largest great white shark caught on camera has resurfaced. A Greenland shark has lived at least 272 years, making the species the longest-lived vertebrate in the world â smashing the previous record held by â¦ The shark is the world's oldest vertebrate â an animal with a backbone â and may have been born in 1505, when King Henry VIII was just 14 years old. Researchers have found an ancient shark in the North Atlantic, believed to be 512 years old, which could be the oldest living vertebrate in the world. Longevity. One Greenland shark was tagged off the coast of Greenland in 1936 and recaptured in 1952. The two biggest sharks â and probably the oldest â were estimated to be 335 and 392 years old, respectively. The team looked at 28 sharks, most of which had â¦ Greenland sharks have been known to live for hundreds of years and consume most of their lives swimming around searching for a mate. The largest shark in the study, at 16.5 feet (five meters) in length, was estimated to be approximately 392 years old. The Greenland Shark can live to be several centuries years old, and one particular member of this shark species is estimated to be 512 years old!
