Greenland shark at Admiralty Inlet, Nunavut, with an Ommatokoita. The Greenland shark is a thickset species, with a short, rounded snout, small eyes, and small dorsal and pectoral fins. [9] The gill openings are very small for the species' great size. Female Greenland sharks are typically larger than males. [13]
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 ...

By another definition, however, maximum life span corresponds to the age at which the oldest known member of a species or experimental group has died. Calculation of the maximum life span in the latter sense depends upon the initial sample size. [1] Maximum life span contrasts with mean life span (average life span, life expectancy), and longevity.
