Genus Psetta is a taxonomic group that encompasses several species of marine flatfishes, known as the turbots. Some synonyms that are used for this group include Scophthalmus, Rhombus, and Platessa. The Scophthalmus genus is comprised of two species of Atlantic turbots, which are found in the waters off Europe and North Africa. Rhombus consists of three species of Pacific turbots, which are native to the waters of the western Pacific Ocean. Platessa is the name of a sole species that is found in the waters of the northeastern Atlantic Ocean and the Mediterranean Sea. All of these species are highly prized by fishermen for their delicious flesh and firm texture.
