Flounders are flat fishes: they lie not on their bellies, but on one side. Their skulls twist as they grow, so that the eye that was originally on the underside migrates around the head, until both eyes come to lie close together on the side facing up, either left or right.
American plaice or dab is a large-mouthed, right-eyed flounder common in deep, sandy or muddy-bottomed waters in the Gulf of Maine and along the Northwest Atlantic continental shelf from southern Labrador to Rhode Island.
Winter flounder is a thick, right-eyed flatfish with dark mottled skin, inhabiting the shallow, muddy bottoms of brackish rivers and estuaries from Labrador to Georgia.
Windowpane flounder is a thin, pale, left-eyed flatfish that lives on the bottom of sandy and muddy bays and estuaries from the Gulf of St. Lawrence to Florida, with concentrations on Georges Bank and the mid-Atlantic. In the Gulf of Maine, most are found in Massachusetts Bay.
Witch flounder is a thin, smooth, right-eyed flatfish found from Labrador to Virginia in deep, muddy-bottomed waters. Generally brown or russet gray.
Yellowtail flounder is a thin, right-eyed flatfish ranging deep, sandy-bottom habitat from Gulf of St. Lawrence to Chesapeake Bay.
