noun - The Greenland shark, also known as the gurry shark or grey shark, or by the Inuit name Eqalussuaq, is a large shark of the family Somniosidae ("sleeper sharks") that is native to the waters of the North Atlantic Ocean around Canada, Greenland, Norway and Iceland. These sharks live farther north than any other shark species. Many of the species' adaptations are due to it being the only truly sub-Arctic species of shark.
It is one of the largest living species of shark, of dimensions comparable to those of the great white shark. Greenland sharks grow to 6.4 meters (21 feet) and 1,000 kg (2,200 lbs.), and possibly up to 7.3 m (24 ft) and more than 1,400 kg (3,100 lb). However, most Greenland sharks observed have been around 2.44–4.8 meters (8.0–15.7 feet) long and weigh up to 400 kg (880 lbs).
