Danish scientists found the ancient creature — which is believed to be 512 years old and is 18ft long. The shark is the world’s oldest vertebrate – an animal with a backbone – and may have been born in 1505, when King Henry VIII was just 14 years old. According to the journal Science, Greenland sharks grow at just one cm a year. So when they discovered a female shark measuring a whopping 18 feet, they knew this creature had to be incredibly old. Scientists used radiocarbon dating to analyse the eye lens of 28

different Greenland sharks. The oldest shark found came out as 392 years old. As radiocarbon dating has a 95% certainty, the shark’s true age could be between 272 and 512 years. If this is true, the shark will have lived through Galileo’s discovery that the Earth orbits the Sun, and the founding of the United States. Incredibly, Greenland sharks don’t reach sexual maturity until the age of 156, but it can happen as young as 134 according to findings. READ MORE
