It is a kind of marine fish, because their bodies are flat. Both eyes are on the upward side of the body, and the color of this side matches the surrounding environment. The downward side of their bodies is white, and there are extremely fine scales on the surface of their bodies. The flounder has only one dorsal fin, extending almost from the head to the caudal fin.

According to the research of marine fishery experts, flounder species are distributed in shallow coastal waters, while flounder species are deeply distributed. The migration modes of halibut in the Yellow Sea are deep water and shallow water, but there are various trends of distribution according to water depth. Due to its close relationship with the cold water mass, halibut is distributed in the northern part of the Yellow Sea.

A flounder is a kind of fish that lives on the bottom of the sea. Among all kinds of flounder, the flounder distributed in coastal shallow waters may have entered people's field of vision at the earliest, while the ancient eastern state of Qi rose earlier and devoted itself to developing the benefits of fish salt. Therefore, "Oriental flounder" has aroused people's infinite reverie because of its unique shape and mystery of living on the seabed.
