They reach sexual maturity at about 150 years of age, and their pups are born alive after an estimated gestation period of 8 to 18 years. The shark is a generalist feeder, consuming a variety of available foods, including carrion. [5]
Scientists estimate the Greenland shark lives at least 250 years. They may live over 500 years. Close-up image of a greenland shark taken at the floe edge of the Admiralty Inlet, Nunavut.
No other vertebrate known has a life span as long as this species; radiocarbon dating of isotopes in the shark’s eye-lens nuclei suggests that the oldest Greenland sharks may be more than 500 years old.
Researchers used radiocarbon dating to determine the ages of 28 of the animals, and estimated that one female was about 400 years old. The team found that the sharks grow at just 1cm a year, and...
Greenland sharks (Somniosus microcephalus) have an average lifespan of at least 250 years but can potentially reach over 500 years old, likely making them the longest-living vertebrates in the...
The researchers found that the oldest sharks could live for about 400 years and reached sexual maturity around age 150. Flabbergasted, scientists from around the world have since been...
Radiocarbon dating of the 28 Greenland sharks' lens nuclei revealed a maximum life span of at least 272 years, according to the study, published August 11 in the journal Science.
The oldest was 392 plus or minus 120 years, they report today in Science. That makes Greenland sharks the longest lived vertebrates on record by a huge margin; the next oldest is the bowhead whale, at 211 years old.
The Greenland shark has by far the longest lifespan for a vertebrate, with an estimated life span of around 400 years.
The Greenland shark is the world’s longest living vertebrate. It can live for 400 years—twice the age of the longest-living land animal, the giant tortoise.
