Sharks are among the most fascinating and ancient creatures in the ocean, with lifespans that vary widely depending on the species. While many smaller sharks live around 20–30 years, some of the largest species can survive for over a century. The Greenland shark, for example, is believed to live up to 150 years or even longer, making it one of the longest-living vertebrates on Earth. In general, larger sharks tend to have slower growth rates, later maturity, and longer lifespans compared to smaller species. This extended life cycle makes them especially vulnerable to overfishing and environmental changes. Sharks play a crucial role in maintaining healthy marine ecosystems by regulating prey populations and supporting ocean biodiversity. Their longevity also provides scientists with valuable insights into aging, survival strategies, and climate adaptation in marine life. However, despite their resilience, many shark species are now threatened due to human activities such as pollution, habitat loss, and illegal fishing. Protecting sharks is essential not only for ocean health but also for the balance of life on our planet. Understanding their lifespan helps us appreciate their importance and the urgent need for conservation efforts worldwide.
