is a right-handed flatfish, which means it lies on its left side, with its eyes on its right side, and its abdomen at its right edge. It is either yellowish or grayish-brown and visibly paler below than above. It has a notably large mouth. Like all members of the halibut group it has a slightly concave tail and symmetrical ventral fins. It can be differentiated by its lateral line, which is nearly straight abreast of the pectoral fin, and by the smooth aspect of its ventral fins.
