Greenland halibut

The Greenland halibut or Greenland turbot ("Reinhardtius hippoglossoides") is part of the Pleuronectidae family and is the only species of the genus Reinhardtius.
It is a deep water fish, ranging between about , and is found in the northern Atlantic and northern Pacific Ocean.
The Greenland halibut is a flatfish, and the left eye has migrated during the fish's development so that it is on the right side of the head.
This fish is used for food and is caught mostly by trawling. Greenpeace thinks the fishery is unsustainable and has added the Greenland halibut to its seafood red list. This designation is widely considered to be based upon limited and unverifiable data.
