The Atlantic halibut (Hippoglossus hippoglossus) is a flatfish of the family Pleuronectidae. They are demersal fish living on or near sand, gravel or clay bottoms at depths of between 50 and 2,000 m (200 and 6,600 ft).
The Atlantic halibut went down a purely XX/XY route, with the male being heterogametic, around 0.9 to 3.8 million years ago. The sex-determining gene for the Atlantic halibut is likely to be gsdf on chromosome 13. [13] The Pacific halibut went down a ZZ/ZW route, with the female being heterogametic, around 4.5 million years ago.

Flatfishes range in size from Tarphops oligolepis, measuring about 4.5 cm (1.8 in) in length, and weighing 2 g (0.071 oz), to the Atlantic halibut, at 2.5 m (8.2 ft) and 316 kg (697 lb). [ 1 ] This article is part of a series on
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 ...

The Pacific halibut, largest of the flatfish, displays its effective camouflage. The largest of the well-known and heavily fished flatfish is the Pacific halibut (Hippoglossus stenolepis). This giant can reach 363 kg (800 lb) and 3 m (9.8 ft), although fish even approaching this size would be extraordinary these days. [132]
