The Greenland shark (Somniosus microcephalus), 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"), closely related to the Pacific and southern sleeper sharks. The distribution of this species is mostly restricted to the waters of the North Atlantic Ocean and Arctic Ocean.
It has the longest known lifespan of all vertebrate species (392 ± 120 years), and is among the largest extant species of shark. As an adaptation to living at depth, it has a high concentration of trimethylamine N-oxide in its tissues, which causes the meat to be toxic. Greenland shark flesh treated to reduce toxin levels is eaten in Iceland as a delicacy.
Usage examples of "greenland shark".
A 20-foot Greenland Shark had invaded the narrow waters between the islands and blundered its way westward, leaving a trail of shredded salmon nets behind, until the weight of twine and anchors it was hauling grew too much for even its mighty muscles and it drowned.
There's the Greenland shark, but they never come down this far, and even if they did, they don't usually bother people.
