This shark may have been alive when Shakespeare’s plays were still being performed for the first time.
It is a Greenland shark, found in the cold waters of the Arctic and North Atlantic.
Scientists estimated that one large female could be around 392 years old.
That means she may have been swimming through the ocean as far back as the 1600s.
Before electricity.
Before cars.
Before America became a country.
Before the modern world existed.
Greenland sharks grow painfully slowly, live in freezing deep water, and may not even reach maturity until around 150 years old.
Researchers estimated their ages by studying proteins in the lenses of their eyes, almost like reading a biological time capsule.
The exact age has a wide margin of error, so we cannot say she was definitely born in 1627.
But the point is still astonishing:
Somewhere in the Arctic, a shark may be older than entire nations.
Still moving.
Still hunting.
Still carrying centuries of ocean history in silence.
