🦈 This shark may be older than your entire family tree.
Meet the Greenland shark: one of the strangest, slowest, oldest animals in the ocean.
Scientists believe some Greenland sharks can live for hundreds of years, with one female estimated to be around 392 years old. That means she may have been swimming before electricity, cars, airplanes, and even before many countries existed.
Basically, while humans were inventing everything, she was slowly cruising through the Arctic like: “cute.” 😭
Greenland sharks live in the cold, dark waters of the Arctic and North Atlantic. They move slowly, grow slowly, and age so slowly that scientists study proteins in the lens of their eyes to estimate how old they are.
And the facts get even stranger.
🦈 They may not be ready to have babies until around 150 years old. Imagine being 149 and still considered too young.
❄️ Their slow metabolism helps them survive in freezing water and may be one reason they live so long.
👀 Many Greenland sharks have parasites attached to their eyes, which may make them partly blind, but they still survive by using smell and other senses.
🐟 They eat fish, seals, squid, and even scavenged animals from the seafloor.
🌊 They are so slow that people sometimes call them “sleeper sharks,” but clearly… slow is working for them.
But this also makes them vulnerable. If a species takes more than a century to reproduce, it cannot recover quickly from overfishing, bycatch, warming oceans, or habitat damage.
So when we protect Greenland sharks, we are not just protecting a shark.
We are protecting a living piece of ocean history.
Somewhere in the deep, cold Arctic, a shark older than modern life as we know it may still be swimming quietly through the dark.
Did you know sharks could live this long? 🦈🌊✨
