Some sharks don’t grow up for 150 years
Greenland sharks swim slowly in the cold waters of the Arctic and North Atlantic Oceans. The cold water slows down their ageing and growth, so they don’t develop into adults until they are 150 years old. Ten years ago, scientists found a 5m (16ft) Greenland shark in the North Atlantic Ocean. They estimated it was about 400 years old.
