The Greenland shark has the longest known lifespan of all vertebrate species. [37] One Greenland shark was tagged off the coast of Greenland in 1936 and recaptured in 1952. Its measurements suggest that Greenland sharks grow at a rate of 0.5–1 cm ( 1 ⁄ 4 – 1 ⁄ 2 in) per year. [ 38 ]
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 ...
Pacific sleeper shark carcasses. The Pacific sleeper shark (Somniosus pacificus) is a sleeper shark of the family Somniosidae, found in the North Pacific on continental shelves and slopes in Arctic and temperate waters between latitudes 70°N and 22°N and in at least two places in the western tropical Pacific near Palau and the Solomon Islands, from the surface to 2,000 metres (6,600 ft) deep.
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. [70] [71] That makes the Greenland shark the longest-lived vertebrate. [72] The maximum lifespan of the freshwater pearl mussel (Margaritifera margaritifera) may be 210–250 ...
Glover’s Reef Atoll sits near “a steep slope that drops from 1,600 feet to 9,500 feet deep, which means there is cold water needed for a Greenland shark to thrive,” Mote Marine reports.
Hákarl (an abbreviation of kæstur hákarl [ˈcʰaistʏr ˈhauːˌkʰa (r)tl̥]), referred to as fermented shark in English, is a national dish of Iceland consisting of Greenland shark or other sleeper shark that has been cured with a particular fermentation process and hung to dry for four to five months. [1] It has a strong ammonia -rich ...
The "OceanXplorers" team looks at a Greenland shark on the ship's Hololab. National Geographic OceanX partnered with Microsoft to create a "holographic laboratory" on the ship.
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. [70] [71]
