The Greenland shark has the longest known lifespan of all vertebrate species. [41] It is estimated that the species has a lifespan of at least 272 years, with the oldest individual estimated to be 392 ± 120 years of age.
The Greenland shark had been estimated to live to about 200 years, but a study published in 2016 found that a 5.02 m (16.5 ft) specimen was between 272 and 512 years old. [82] [83] That makes the Greenland shark the longest-lived vertebrate. [84] The maximum lifespan of the freshwater pearl mussel (Margaritifera margaritifera) may be 210–250 ...
Greenland sharks are the longest-living vertebrates in the world, according to NOAA. They can live “at least 250 years” but might reach “over 500 years” in age. Most of the shark’s long ...
Earlier estimates suggested the Greenland shark (Somniosus microcephalus) could reach about 200 years, but a recent study found that a 5.02-metre-long (16.5 ft) specimen was 392 ± 120 years old (i.e., at least 272 years old), making it the longest-lived vertebrate known. [72] [73]
Greenland shark. Scientists recently discovered that this extraordinary fish was the longest-living vertebrate on earth. One female in the north Atlantic was found to be 400 years old.
The rarely seen Greenland shark is a sluggish creature, slowly swimming through the deep waters of the North Atlantic and Arctic oceans. The polar fish is the only species of shark that can ...

For sexually reproducing planaria: "the lifespan of individual planarian can be as long as 3 years, likely due to the ability of neoblasts to constantly replace aging cells". Whereas for asexually reproducing planaria: "individual animals in clonal lines of some planarian species replicating by fission have been maintained for over 15 years".
