A shark that lives for almost four centuries could hold the secret to a longer life. Greenland sharks, with a lifespan of up to 392 years, are thought to possess unique longevity genes now being searched for by scientists. A team has taken fin clippings from almost 100 Greenland sharks, including some individuals born in the 1750s. Already the researchers have mapped out all the 16ft shark’s mitochondrial DNA – genetic material held in tiny battery-like bodies in cells that supply energy.
