This shark may have been cruising the ocean before the United States even existed. š¦
Meet a female Greenland shark estimated to be about 400 years old. Scientists say she could be even older, with an age range stretching up to around 512 years.
Wait, what?! Her life started long before cars, long before powered flight, and centuries before the first photograph was ever taken.
How do researchers know? They used radiocarbon dating on tissue inside the eye lenses, which keeps a chemical record from early life. Basically, the eyes are a time capsule. š
Hereās another twist. These sharks grow painfully slowly and are thought to take more than a century to reach sexual maturity. Imagine waiting 150 years just to become an adult.
They live in the cold waters of the North Atlantic and Arctic, mostly deep below the surface where sunlight barely reaches. Theyāre also not picky eaters. They scavenge, and theyāve been known to eat seals and other fish.
Their slow growth makes them vulnerable, so every adult matters to the population. Thatās a big deal for an animal that has been around for centuries. š
So hereās the takeaway: if a shark can cruise through four centuries of history without rushing, maybe your Monday can take its time too.
