A marine fish of the family Oplegnathidae (illustration) in the order Perciformes. Like the punctatus punctatus (illustration) of the same family, it is characterized by stacked teeth with the gaps between them filled with calcareous matter, forming a beak-like shape. It has seven wide horizontal black stripes on its side, and is also called Shimadai or Shichinoji. As it grows, these stripes become less distinct and the whole fish turns black. As the area around the mouth of older adult fish turns black, it is also called Kuroguchi, Kuchiguro, and Black Mask, especially in the Kansai region.
