Overview of Flatfish

Flatfish are a group of fish with a unique body shape, characterized by having both eyes on one side of their head.

This adaptation allows them to lie flat on the ocean floor and easily blend in with their surroundings.

They are found in oceans all around the world and are an important commercial and recreational fishery.

There are many types of flatfish, including the popular flounder, sole, halibut, turbot, and plaice.

Each species has its own unique characteristics, but they all share the same flattened body shape and asymmetrical head.

Flatfish are typically bottom-dwelling fish, living in sandy or muddy areas near the shore or on the continental shelf.

They are often caught using bottom trawls or gillnets, and are prized for their delicate flavor and firm texture.

Flatfish are an important part of the marine ecosystem, serving as both predator and prey. They feed on a variety of small fish, crustaceans, and other invertebrates, while larger flatfish like halibut and turbot can feed on squid and even other fish.

Flounders

Flounders are a group of flatfish that are found in both freshwater and saltwater environments.

They are characterized by their oval-shaped bodies and their eyes that are both on one side of their head.

There are many different species of flounders, including left-eyed flounders, right-eyed flounders, starry flounders, southern flounders, and more.

Soles

Tonguefish are a type of flatfish that are found in the Atlantic Ocean, the Pacific Ocean, and the Indian Ocean.

They are characterized by their elongated bodies and their eyes that are both on one side of their head.

Some of the most common types of tonguefish include the bristle mouthed tonguefish and the yellowtail tonguefish.

Habitat and Distribution

Flatfish are a diverse group of fish that are found in a variety of habitats around the world. They are known for their flattened body shape, which allows them to blend in with their surroundings and avoid detection by predators.

The habitat and distribution of flatfish vary depending on the species, but they can generally be classified into two categories: freshwater habitats and saltwater habitats.

Freshwater Habitats

While most flatfish species are found in saltwater habitats, there are a few species that are adapted to freshwater environments.

These species are typically found in rivers, streams, and lakes, and they are most commonly found in North America, Europe, and Africa.

Some of the most well-known freshwater flatfish species include the European flounder, the starry flounder, and the yellowfin sole.

Freshwater flatfish are adapted to living in environments with low salinity levels, and they are often found in shallow water near the shore.

They are also able to tolerate a wide range of water temperatures, which allows them to survive in a variety of different climates.

Saltwater Habitats

The majority of flatfish species are found in saltwater habitats, including oceans and brackish waters.

They are found in a variety of depths, from shallow coastal waters to deep ocean trenches, and they are distributed throughout the world’s oceans.

Some of the most common saltwater flatfish species include the Atlantic halibut, the Pacific halibut, and the sole.

Saltwater flatfish are adapted to living in environments with high salinity levels, and they are often found in deeper water than their freshwater counterparts.

They are also able to tolerate a wide range of water temperatures, which allows them to survive in a variety of different climates.

In North America, flatfish are commonly found in California, where they are an important commercial and recreational fishery.

Other regions where flatfish are commonly found include Europe and Africa. The distribution of flatfish species varies depending on the species and the habitat they are adapted to, and they can be found in a variety of different environments around the world.

Classification of Flatfish

Flatfish belong to the order Pleuronectiformes, which includes over 800 species of fish. This order is divided into three suborders: Psettodoidei, Pleuronectoidei, and Soleoidei.

Flatfish are found in the suborder Pleuronectoidei, which includes three families: Soleidae, Bothidae, and Cynoglossidae.

The family Soleidae includes over 60 species of flatfish, commonly known as soles. They are found in both freshwater and saltwater environments.

The family Bothidae includes over 150 species of flatfish, commonly known as turbots and flounders.

They are found in saltwater environments and are mostly bottom-dwellers. The family Cynoglossidae includes over 130 species of flatfish, commonly known as tonguefish and sole. They are found in saltwater environments and are mostly bottom-dwellers.

Common Names

Flatfish have a variety of common names depending on the species and region. Some common names for flatfish include sole, flounder, turbot, halibut, and tonguefish.

The scientific names of flatfish are based on their family, genus, and species. For example, the scientific name for the common sole is Solea solea, and the scientific name for the Atlantic halibut is Hippoglossus hippoglossus.

The classification of flatfish is based on their physical characteristics, including their flattened body, asymmetrical head, and position of their eyes.

Flatfish have both eyes on one side of their head, and the side they lay on determines their type. The term heterosomata is used to describe this characteristic of flatfish.
