The flounder is a species of fish in the plaice family Platyhelminthes.

Plaice, also known as flounders inhabit shallow, sandy bottoms and prey on small fish and shrimp. They are particularly well adapted for benthic life on the seabed. Due to their flattened body. The eyes are the same on the upward-facing side of the body, and the color of this side matches their surroundings well; the downward-facing side of their body is white.

The flounder has extremely fine scales on the surface of its body. Flounder have only one dorsal fin, which extends from the head almost to the caudal fin. They live mainly in temperate waters and are an economically important fish in temperate seas.

Habitat

Different species of flounder have different methods and routes for moving their eyes. The skull of the flounder is made of cartilage. When the flounder's eyes begin to move, the cartilage between the flounder's eyes is first absorbed by the body. In this way, there is no obstacle to the movement of the eyes. The movement of the flounder's eyes is a result of changes in the flounder's internal structure and organs as well. The flounder is no longer adapted to a floating life and has to lie across the bottom of the sea.

The flounder is a valuable seafood. It is called flounder in fisheries. The body of the flounder is usually 25 centimeters to 50 centimeters long, and the largest flounder is 70 centimeters. Turbot will do short-distance cluster migration according to the change of seasons. Along the coast of China, turbot has a wide distribution. Fishermen in the Yellow Sea and Bohai Sea use bottom trawling nets to catch turbot. Fresh flounder can be eaten or canned. The liver of turbot can also be refined into cod liver oil.
