Danish scientists speculate that they’ve discovered the longest-living vertebrate: a shark in Greenland that could be as old as 512 years of age. If the analysis turns out to be correct, the shark could be a possible witness to Galileo Galilei’s conviction of heresy and the arrival of Dutch settlers in New York City, and perhaps even, events dating far back in history. Moreover, the female shark would have been no less than 151 years of age when the American Founding Fathers marked the Declaration of Independence.
Amazingly, the average period of sexual development for Greenland sharks is 156. Nonetheless, it could likewise happen at as a youthful age as 134, as indicated by the studies conducted by Danish scientists.
The length of a shark can be used to decipher its age. In this case, the scientists found the shark to be the oldest among the group of 28 Greenland sharks examined. Also, a technique called radiocarbon dating was used wherein the eye lens of 28 Greenland sharks was scrutinized. Empirically, the oldest shark to be studied was approximately 392 years old.
The growth rate of Greenland sharks is known to be slow — about one centimeter per year. Therefore the discovery of this particular female shark measuring about 18 feet was historical, quite literary. It is clear the shark had experienced a few centuries of antiquity.
