Greenland sharks, found in the deep North Atlantic, are Earth's longest-living vertebrates, with some reaching nearly 400 years of age. Scientists determined their age using radiocarbon dating on eye lens proteins. These sharks reach sexual maturity only after 100 years. Their longevity is attributed to a slow metabolism and an extraordinary DNA repair mechanism identified in a September 2024 genetic study. This discovery could provide insights into anti-aging research for humans. https://tamil.indianexpress.com/science/earths-longest-lived-vertebrate-how-a-single-eye-protein-unlocked-the-greenland-sharks-400-year-lifespan-12008841 #creator program
