15 Types of Flat fish to Eat in the Ocean


Brill is a variety of names that are based on various locations or even countries. In Finland, there is a Finnish name for brill is, Silokampela, and the name in Portugal, the Portuguese name is Rodovalho.

Brill fish Types of Flatfish

The Romanian residents refer to the fish Calcan, and the Germans call this fish Glabutt. The Dutch inhabitants of Holland, as well as the Netherlands, refer to the fish Giet and for Spanish, the name is Remol. The Italian term for Brill is Rombo Liscio, and for the French locals, Barbue is the name for brill.

 The size of the Brill gauges is between thirty and fifty centimeters, according to certain reports. However, in other documents, they do range from forty to seventy-five centimeters.

In contrast to turbots, these fish are cheaper since they are commercially caught. They can also be found in all waters of the United Kingdom. Brill is found on sandy or mixed substrates as well as in waters that are less than fifty meters.

The brill’s young fish are at shallow depths for twelve to 24 months or up to 2 years. They generally spawn or propagate in spring, but not until springtime of the summer. The spawning takes place in water that is at least ten to twenty meters in depth. The top of the brill is devoid of tubercules and is smooth too.


Dab is a flatfish types belonging to the genus Limanda, a family of Pleuronectidae which is located throughout the North Atlantic and North Pacific. Dabs are Flat fish that have eyes on the right which means that the eyes are typically located on the right side of the head.

Dab Fish Types of Flatfish

In the soles of European lakes is L. Limanda, which is a plentiful food source and important fish. It’s small, typically less than 25cm (10 inches) long, and is light brown with dark spots.

 Other species include the yellow-tailed or the rusty sole (L. theodorina), which is a reddish-brown Western Atlantic fish with spots of rust and yellowtail. Yellowfin sole, also known as the Alaskan sole (L. aspera) Flat fish that is brownish from the North Pacific. 

The Long-headed sole (L. Proboscidea) which is a brown North Pacific fish with light yellow spots on their edges body. The name dab can also be applied to other flatfish types like the Sanddab ( American plaice, also known as the rough dab (see plaice).


 They typically have one eye on each side. This isn’t a way of security. However, certain members of this family might have eyes on the left side in the same manner that certain individuals are left-handed. The flounders with left-handed stipulations make up approximately a third of the population.

Flounder Fish Types of Flatfish

Flounders can be differentiated from other Flat fish through the angle between the midpoint of the dorsal as well as the anal fins. The other members of the family also have fins that are more rounded. They also stand out with bony tubercles that run along the lateral line, which creates a slight ascending curve that crosses the pectoral fin.

The lower portion is nearly always white. The flank which has the eyes is different in accordance with the background. It can range from brown to greenish and is uneven to spots. The spots can be rusty red (can be confused when confused with plaice).


 is part of the family known as pleuronectidae which includes other well-known fish like flounder. It’s often described as a substitute for the sole, and since it is often presented in fillets, it can be difficult for the customer to distinguish it.

It has an oval long, and fleshy body. It has both eyes to the right of the head and looking to the right. Its appearance is quite bizarre as it’s similar to flounders. However, it is much bigger.

Halibut is thicker, longer, and heavier than other Flatfish. The embryos and young specimens show bilateral symmetry—however, the proportions of its body shift in the course of growth.


Megrim is abundant in the UK as well as in southern Norway, Iceland, France, and Spain and a little less within the Mediterranean. As per FAO (Food and Agriculture Organization which is an agency of the United Nations), total landings across these regions are around 15,000 tonnes per year, and the UK is part of the total at 3000 tonnes.

The majority of which are believed to be shipped to Spain, which is where megrim is more well-known. It’s referred to as Gallo, which is a Spanish word meaning rooster.

 In reality, 15,000 tonnes overstates the reality since megrim is an extremely inexpensive fish, and many fishing vessels have had the habit of historically (and most likely will are continuing to do so) to throw it away due to the fact that the price it fetches isn’t worth the hassle of dealing with it.

 Once it’s landed in the water, it’s usually between 500g and 1500g and around 35cms in length. It has a light brown skin that is topped by massive, rough scales and a few spots and a somewhat transparent aspect.

A naturalist from the 18th century, Thomas Pennant, perhaps stated this more precisely: “The colour of the upper portion of the body is cinereous , a greyish us all brown, obscured in places and obscurely visible and the lower part white, colored by the red.” (The the same Thomas Pennant though the megrim looked like”Holibut” in appearance “Holibut.”

We’ll leave the fact that it resembles the “Holibut.”) There’s a species that is very similar called the megrim with four spots (Lepidorhombus boscii) with four grey spots that are completely indistinguishable.


Is also known as tongue sole. It’s one of the tiny flatfishes that inhabit the oceans, belonging to the family Cynoglossidae, which are that are found in tropical waters, particularly in Asia.

Tongue fish

Tonguefish are flat and drop-shaped fish that have small eyes, located on the right side with long dorsal as well as anal fins that connect with that of the tail fin. The majority of tonguefish are smaller than 30 cm (12 inches). Some are eaten for food, but the majority, due to their small dimensions, have little commercial value.


It’s white fish that is flat in appearance and with saltwater. It is found in bottoms that are covered by dirt or sand and expose its eyes only. They are found at 50 percent of depth, which is approximately 100 meters. It is a fluorescent fish that lives in warm temperatures.

It reproduces throughout the winter season, and the egg eggs can be described as pelagic.

Sole fish Types of Flatfish

Sole is considered to be the best Flatfish, both for its culinary qualities. It is only exceeded by Turbot and its abundance. Its inactivity is higher in the daytime because it has primarily nocturnal habits.

 Carnivores eat a diet of eating tiny fish and crustaceans and bottom invertebrates, particularly annulids. The hunter is camouflaged in the sand, waiting for his prey.


Plaice is like flounder, plaice is found only in the waters surrounding Finland. It can reach a little larger size than flounder at times, even inside the Baltic. However, the sollas found from those caught in the Finnish Sea areas have not been very big.

Plaice Fish

Skin is, in fact, soft. In contrast to flounders and squid, there aren’t any bones in the form of rows that are above and beneath the line of lateral. The plaice has between 4 and 7 bony bumps in the area behind the eye. Fins are more round than flounders.

A fin with a minimum of 49 or more rays. That of flounder usually ranges between 35 to 46. Plaice is red with spots on its dark topside; however, it isn’t an exact method of identification because flounders typically have similar spots.

 Pacific Sanddab

The Pacific Sanddab is flat fish types that is with a light brown color, with occasional orange or white spots. They’re known as a “left-eyed” flounders with eyes on both their left sides of the head of the Sanddab. They’re bottom-dwelling species, which range from Baja up to the Bering Sea.

Pacific Sanddab Fish

While they are located in depths of 30 bis 1800 feet, they are the most plentiful, between 120 and 300 feet. They consume small fish like squid eggs and crustaceans. Sanddabs are typically caught commercially by bottom trawlers and occasionally smaller boats using hooks and lines. The flesh of the Pacific Sanddab is mild, sweet as well as low-fat.

It comes with an apricot-colored skin that is delicious when served crisp–Sanddab sandwiches are a favorite local food! Sanddabs are small; the majority range from 7 to 10 inches and weigh around 1 lb when fully mature. However, they’ve been discovered as big up to 16inches and 2lbs. They’re great when pan-fried, broiled, or baked and served with a simple salad or vegetable dish.


Turbot is saltwater and whitefish, it is part of the Scophthalmidae family. It is found in the sea, ranging from 10 and 200 meters in depth. It is devoid of scales. For the initial two years, they remain close to the shore.

Turbot Fish

As they age, they move to higher amounts of money; however, it is not quite the mid-point of the existing platform and can be reproduced. When they reach sexual maturity, they weigh 15 cms (males) and 20cms (females). It is able to lay up to 9 million roe, which can later develop into pelagic larvae.


Pleuronectoidei is one of the bony fish suborders. The species include 782 Pleuronectoidei and 12 families, and 132 genera. This suborder has existed since the late hauterivian era. It comprises groups such as Bigeye Flounders, Southern Flounders, and Turbots.


The family is known as “left-eye flounders” due to the fact that most species are in the bottom of the ocean on their right side, with both eyes on their left side.” The family is distinct by having spines in the snout and close to the eyes. Flatfishes typically reside in the soft bottom and are included in the catches of trawlers.


Their color blends beautifully with the bottom, and they are able to swiftly alter their color to blend with the substratum. Their diet is composed mostly of crustaceans and fishes. The tropical-to-warm family includes 131 species spread across 20 genera.

Within the eastern tropical Pacific, there are five species in four genera found in shallow waters, which include the one Indo-Pacific and four species that are endemic, and one genus that is endemic.


The Scophthalmidae can also be described as a group of Flat fish that is found within the North Atlantic Ocean, Baltic Sea, Mediterranean Sea, and the Black Sea. The fish of this family are often referred to as turbots.


However, this term could refer to the species Scophthalmus Maximus in addition. An analysis of cladistics shows that this is a monophyletic family of Nine types of flatfish are included, and the most massive can reach 1 m in length. Certain species of the family are commercially fished.

Eyes are on their left. Preopercular margins are not present. A large mouth that is prominent in the lower jaw. The pelvic fins’ bases extend. Benthic in the continent shelf. They feed on benthic invertebrates as well as tiny fish. Certain species can reach a certain size and have enough to make them important to fishing.


Scaldfish is a pale left-eye flounder that is brownish with noticeable black spots in the rear end of the dorsal as well as the anal fins. The outer edge of the pectoral fin on the eyed side and the extremely long anterior dorsal-fin male rays that are greater than 5 cm in length.


Petrale Sole

Petrale Sole is an oval-shaped or round flounder with a mouth that is large and two eyes on the right side. The side that is blind is white, while the side with eyes is dark to light brown. Flat fish quality is variable, and the most desirable ones possess uniform color and do not have to bleed, as stated by certain customers.

Types of Flatfish Petrale Sole

Petrale sole is sold fresh and frozen, as whole and skinless in fillets. Petrale sole is a great source of protein that is low in fat along with calcium and other essential nutrients. The ideal time to purchase petrale is in the winter months, where prices are lowest. Since larger Flat fish can fetch more, smaller portions could be worth the price as per certain buyers.
