Description

The Greenland halibut is a large flatfish of the righteye flounder family (Pleuronectidae) from the cold northern Atlantic and Arctic Ocean. The species grows to about 1.1 metres and has an elongate body with both eyes on the right side, but unlike most flatfishes also a well-developed, dark-coloured blind side, related to its partly active, pelagic hunting behaviour. It lives at great depth and tolerates bottom temperatures of -0.5 to 6 degrees. As a predator it hunts fishes, squid and crustaceans. The Greenland halibut is a very important commercial fish; owing to fishing pressure it is listed as Near Threatened (NT). It is harmless to humans.
