Greenland sharks have the longest lifespan of any known vertebrate, estimated to be between 250 and 500 years. [4] They are among the largest extant species of shark, reaching a maximum confirmed length of 6.4 m (21 ft) long and weighing over 1,000 kg (2,200 lb).
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. [75] [76] That makes the Greenland shark the longest-lived vertebrate. [77] 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 ...
These remarkable sharks can live for up to 400 years, surpassing the previous record-holder, the bowhead whale, which can reach around 211 years. A Greenland shark alive today could have been ...
There are living Greenland sharks that were around at the same time as George Washington’s presidency in 1789. That’s because the life expectancy of a Greenland shark is over 500 years.
Olm (Proteus anguinus) – 102 years; Eastern box turtle (Terrapene carolina) – 138 years; Red sea urchin (Strongylocentrotus franciscanus) – 200 years; Rougheye rockfish (Sebastes aleutianus) – 205 years; Ocean quahog clam (Arctica islandica) – 507 years; Greenland shark (Somniosus microcephalus) - 250 to 500 years
Some examples of maximum observed life span of animals thought to be negligibly senescent are: Rougheye rockfish: ... 507 years [25] Greenland shark: 400 years [26]
The polar fish is the only species of shark that can withstand the freezing temperatures year-round. The large sharks also live to be more than 400 years old, and some of them may have been alive ...
