The Greenland halibut or Greenland turbot (Reinhardtius hippoglossoides) belongs to the family Pleuronectidae (the right-eye flounders), and is the only species of the genus Reinhardtius. It is a predatory fish that mostly ranges at depths between , and is found in the cold northern Atlantic, northern Pacific, and Arctic Oceans. It has a variety of other English vernacular names, including black halibut, blue halibut, lesser halibut, and Newfoundland turbot; while both Newfoundland turbot and Greenland turbot are in common use in North America (sometimes even without the location, just "turbot"), these names are typically not used in Europe, where they can cause easy confusion with the true turbot (Scophthalmus maximus). The Greenland halibut is fished commercially across its range with disputes over the fishing rights for this species in the Atlantic Ocean off Canada resulting in the Turbot War of the mid-1990s (a "war" without any injuries or casualties). 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. However, in this fish, it has not moved as far as in bottom-dwelling flatfish and the fish can probably see forwards. The Greenland halibut can swim in a vertical position and both sides of its body are a speckled brown colour, but the left side is rather paler than the right. The Hellefisk Fjord in Greenland is named after this fish, hellefisk being the Danish name for Greenland halibut. Description Its morphology with the left eye positioned on the dorsal ridge of the forehead gives it an appearance of a cyclops when looking straight at it. The central position of the left eye in the Greenland halibut probably gives it a much wider range of peripheral vision in comparison to other flatfish, where the eye has migrated completely. Its body shape is elongated and compressed dorsoventrally and muscles on both sides are equally developed. Both sides are pigmented, but the left blind side is slightly lighter in color than the right side. The maximum length is about and the maximum weight is about , the normal length is and they usually weigh . Distribution and habitat The Greenland halibut is a cold-water species found at depths from near the surface to , but mainly between . It is mainly found in waters with temperatures from , but has also been observed at subzero temperatures
