Pleuronectoidei

Flatfish are a group of ray-finned fish belonging to the suborder Pleuronectoidei and historically the order Pleuronectiformes (though this is now disputed). Their collective common name is due to their habit of lying on one side of their laterally-compressed body (flattened side-to-side) upon the seafloor; in this position, both eyes lie on the side of the head facing upwards, while the other side of the head and body (the "blind side") lies on the substrate. This loss of symmetry, a unique adaptation in vertebrates, stems from one eye "migrating" towards the other during the juvenile's metam

The Citharidae or largescale flounders are a small family of flounders with four genera. Three genera are restricted to the Indo-Pacific, while Citharus is from the Mediterranean and East Atlantic (off northwest Africa). There are a total of seven species. Species reach lengths ranging between .

They are demersal fish, found at the bottom of oceans around the world; some species will also enter estuaries.

The Poecilopsettidae are a family of flatfish, comprising three genera and 21 species. Species are typically demersal, living on marine bottoms at depths between in the Indo-Pacific and northwestern Atlantic; the deepest recorded occurrence is in the deepwater dab, Poecilopsetta beanii. Sizes range from in length, though most species are usually under long. Diets consist of zoobenthos.

Amphistium paradoxum (from , 'on both sides', 'sail', and 'extraordinary'), the only species classified under the genus Amphistium and the family Amphistiidae, is a fossil fish which has been identified as a Paleogene relative of the flatfish, and as a transitional fossil. In a typical modern flatfish, the head is asymmetric with both eyes on one side of the head. In Amphistium, the transition from the typical symmetric head of a vertebrate is incomplete, with one eye placed near the top of the head.

Citharoides is a genus of citharid flounders native to the Indian and West Pacific Oceans.

Rhombosoleidae is a family of flatfish, comprising nine genera and 19 species; all members of this family are right eye flounders with asymmetrical pelvic fins. Species are typically demersal, living on bottoms in temperate marine waters on the continental shelf, although some species of Rhombosolea enter fresh water in New Zealand. Most are restricted to waters around Australia and New Zealand, though the Indonesian ocellated flounder, Psammodiscus ocellatus, occurs in Indonesia.

Heteronectes is a fossil fish which has been identified as a primitive flatfish, dating to the early Eocene (Lutetian stage) of France. The genus contains a single species H. chaneti.

Eobothus ('dawn Bothus') is an extinct genus of very small, fossil marine flatfish known from the Eocene. It is one of the oldest flatfish known from fossil remains.
