Greenland Halibut

The Greenland Halibut, also known as Greenland Turbot (Reinhardtius hippoglossoides), is the sole species in the genus Reinhardtius and part of the right-eye flounder family, Pleuronectidae. This predatory fish primarily dwells at depths of 500 to 1,000 meters (1,600–3,300 feet) in the cold northern Atlantic, Pacific, and Arctic Oceans.

As a flatfish, the Greenland Halibut's left eye migrates to the right side of its head during development. Unlike other bottom-dwelling flatfish, its eyes are positioned allowing forward vision. It can swim vertically, and both sides of its body are speckled brown, with the left side being slightly paler.

The fish is pigmented on both sides, but the left (blind) side is a lighter shade than the right. It can grow up to 120 cm (3.9 ft) in length and weigh around 45 kg (99 lb), although the typical size is 80–100 cm (2.6–3.3 ft) and weight ranges from 11–25 kg (24–55 lb).

Greenland Halibut are opportunistic predators. Smaller individuals under 20 cm primarily consume crustaceans like amphipods, while larger ones shift to a diet of shrimps and fish, with those over 60 cm mainly feeding on other fish.

Commercially fished by countries like Russia, Norway, Iceland, Germany, Spain, Greenland, and Canada, Greenland Halibut are caught using various methods such as bottom trawls, longlines, and gillnets.
