The Greenland Halibut (Reinhardtius hippoglossoides) grows to 60 cm.
A long, slender, "right-sided" flatfish, with the left eye on the side of the head. The blind side is significantly pigmented.
Breeds in April-July in depths of 700-2,000 m. The young inhabit waters of 50-200 m until 12-25 cm, when they move into deeper water.
Found in very deep water (to 2,000 m), where it swims "upright", like a normal fish.
The Greenland halibut hunts codling and smaller species of fish, and also takes deep-sea prawns.
This is an Arctic species, with its southerly limits off the continental shelf to the west and north of the UK.
