Bowhead whales can live up to 200 years and Greenland sharks can live over 500 years.
"you know, the bowhead whale lives 200 years old, you know, the Greenland shark can live 500-plus years old." (said at 0:48:33)
The speaker bundles two longevity claims. The claim that bowhead whales can live approximately 200 years is supported; genomic and biochemical studies establish that bowhead whales (Balaena mysticetus) have an estimated maximum lifespan exceeding 200 years, making them the longest-lived mammal. However, the claim that Greenland sharks live '500-plus years' is overstated. Landmark radiocarbon dating of Greenland shark (Somniosus microcephalus) eye lenses estimated the lifespan of the largest individual at 392 ± 120 years (a 95.4% probability range of roughly 272 to 512 years). While 512 years represents the extreme upper statistical bound of the confidence interval, the mean estimate is approximately 390 years, not a definitive 500+ years.
