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 500 and 1,000 m (1,600–3,300 ft), and is found in the cold northern Atlantic , northern Pacific ...
The Pacific Halibut population remains largely genetically homologous throughout their range, but there is some variation of life-history traits on a geographic gradient. [16] Despite its large range, the populations of Greenland Halibut remain largely homogenous due to a lack of barriers for gene flow between its four major populations. [19]
Although the bulk of its area is covered by ice caps inhospitable to most forms of life, Greenland's terrain and waters support a wide variety of plant and animal species. The northeastern part of the island is the world's largest national park. The flora and fauna of Greenland are strongly susceptible to changes associated with climate change. [1]
Halibut size is not age-specific, but rather tends to follow a cycle related to halibut (and therefore food) abundance. The native habitat of the Atlantic halibut is the temperate and arctic waters of the northern Atlantic, from Labrador and Greenland to Iceland, the Barents Sea and as far south as the Bay of Biscay and Virginia.

They are found on the bottoms of oceans around the world, with some species, such as the Atlantic halibut, Hippoglossus hippoglossus, being found down to 2,000 m (6,600 ft). The smaller species eat sea-floor invertebrates such as polychaetes and crustaceans , but the larger righteye flounders, such as H. hippoglossus , which grows up to 4.7 m ...
An isolated group of polar bears living in southeast Greenland has surprised scientists with its ability to survive in a habitat with relatively little sea ice.
Neolithodes grimaldii, the porcupine crab, [2] is a species of king crab in the family Lithodidae.This large red crab is found in cold deep waters in the North Atlantic and often caught as a bycatch in fisheries for Greenland turbot (Greenland halibut).
Example pelagic fish are capelin, herring, whiting, mackerel and redfish, There are, however, a few demersal species that are straddling, such as the Greenland halibut migrates in feeding/spawning migrations to Greenland in the west and to the Faeroes in the east. [4] Straddling stock can be compared with transboundary stock.
