This flatfish is very thin and not meaty or big enough to be popular with anglers. On top it is brown in color and heavily spotted with white and darker brown. Its underside is white and nearly transparent; on small individuals the internal organs can be seen.
The windowpane is a saltwater fish. We catch many in New York Harbor. While they can reach a length of eighteen inches, those that come up in our nets are seldom more than twelve inches long.
