Man is not even an also ran in the longevity stakes according to GROK.

The Greenland shark has an estimated life expectancy of at least 250–500 years, making it one of the longest-living vertebrates on Earth. Studies using radiocarbon dating of their eye lenses suggest some individuals may live over 400 years, with sexual maturity reached around 150 years. Their slow metabolism and cold, deep-water habitat contribute to this extreme longevity.

Bowhead Whale: Up to 200+ years. Radiocarbon dating of harpoon points in blubber suggests some live over two centuries.

Galápagos Tortoise: Around 150–200 years. Famous examples like Harriet lived over 170 years in captivity.

Ocean Quahog Clam: Over 500 years. One specimen, "Ming," was dated to 507 years via shell ring counting.

Galápagos Tortoise: Around 150–200 years. Famous examples like Harriet lived over 170 years in captivity.

Ocean Quahog Clam: Over 500 years. One specimen, "Ming," was dated to 507 years via shell ring counting.

Rougeye Rockfish: Up to 205 years. Age determined by otolith (ear bone) analysis.

Tuatara: Around 100–150 years. These reptiles have slow metabolisms and can live over a century in the wild.Hydra: Potentially immortal. These simple freshwater organisms can regenerate cells indefinitely under ideal conditions.

Parrot (e.g., Macaws): Up to 80–100 years. Some captive parrots, like Cookie the cockatoo, lived nearly a century.

Longevity often correlates with slow metabolisms, stable environments, or regenerative abilities. Deep-sea or cold-climate species, like the Greenland shark, tend to dominate the upper ranges.
