Sole has a flattened elongated body. It can burrow itself almost completely in a sandy or muddy bottom, where it mostly lives. Just like most other flatfish species, both eyes are located on the right side of the body. It looks for worms using feelers hanging under its chin. Sole is a nocturnal hunter. At night, this species sometimes swims far above the sea floor where the sea current carries it to other territories. When it comes time to spawn, it migrates to the same grounds in the southern North Sea every year.
