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 ...
That’s because the life expectancy of a Greenland shark is over 500 years. ... The average adult human has 2,000-4,000 taste buds, and despite what you may have been taught, they are not visible ...
Greenland shark (Somniosus microcephalus) - 250 to 500 years; ... The European lobster has an average life span of 31 years for males and 54 years for females.
Unlike most sharks and other vertebrates, which have hard tissues like spines that form growth rings (much like the rings inside a tree trunk), Greenland sharks lack these structures, making age ...
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 ...

Rats, mice, and hamsters experience maximum life-span extension from a diet that contains all of the nutrients but only 40–60% of the calories that the animals consume when they can eat as much as they want. Mean life span is increased 65% and maximum life span is increased 50%, when caloric restriction is begun just before puberty. [57]
