Some individuals swimming beneath Arctic ice today may have hatched in the early 1600s, meaning they survived the rise and fall of empires, the Industrial Revolution, and two World Wars while moving silently through polar darkness.
This extreme longevity challenges assumptions about vertebrate aging, metabolic limits, and DNA repair, reshaping research into lifespan biology and raising questions about what other deep sea organisms may endure for centuries unseen.
