The Greenland halibut (Reinhardtius hippoglossoides) is a flatfish that lives on the sea floor in the cold waters of the Arctic Ocean and the North Atlantic. It prefers waters below 4 degrees Celsius and a sandy seabed. They can be found at depths ranging from 200 to 2000 metres, from the east coast of North America to the western and eastern coasts of Greenland, across the North Atlantic to the Norwegian coast and all around the Barents Sea.
Its meat is snowy white with a delicate and sweet taste. The Greenland halibut is slightly different from other halibuts as it does not have two distinctive sides. It is dark in colour – brown or charcoal – sometimes with a few lighter spots on the sides. The left side is slightly paler. Its muscles are equally well developed on both sides making it possible for the Greenland halibut to swim in a vertical position. It is a carnivore and mostly eats prawns, krill, capelin and redfish.
