The Pacific halibut went down a ZZ/ZW route, with the female being heterogametic, around 4.5 million years ago. [13] [14] The master sex-determining gene of the Pacific halibut is located on chromosome 9 and it is likely to be bmpr1ba. [15] The gene sox2 is likely to play the same role in the Greenland halibut.

Large-tooth flounders or sand flounders are a family, Paralichthyidae, of flounders. [1] [2] The family contains 14 genera with a total of about 110 species.They lie on the sea bed on their right side; both eyes are always on the left side of the head, while the Pleuronectidae usually (but not always) have their eyes on the right side of the head.
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 ...
