Greenland sharks grow to 6.4 m (21 ft) and 1,000 kg (2,200 lb),[7][8] and possibly up to 7.3 m (24 ft) and more than 1,400 kg (3,100 lb). The type, amount, and duration of parental care the young receive are unknown, but scientists speculate that, like other shark species, Greenland sharks are independent from birth. [9] Small Greenland sharks eat predominantly squid, while the larger sharks that are greater than 200cm were discovered eating prey such as epibenthic and benthic fishes as well as seals. They have a slow growth rate, late maturity period, and low fecundity, making the management and conservation of this species very important.

Greenland sharks are large fish, comparable in size to great whites and in appearance to sleeper sharks. The Greenland shark {Lacmargus borealis) is the notable exception to the order. As a result of their low productivity and extreme longevity, this species is particularly susceptible to overfishing. They have short, rounded snouts, small eyes, and small but sharp teeth. The hemoglobins also have a lower affinity for O2 compared to temperate sharks. [24][25], The shark is often colonized by the copepod Ommatokoita elongata, which attaches itself to the shark's eyes. It can reach a length of 7 metres (23 feet) and a weight of 1,025 kg (2,260 pounds) when fully grown, but most are between 2 and 4 metres … marine animal CC BY-SA 4.0.
