Hippoglossoides elassodon

The blind side is white and translucent in places. Both dorsal and anal fins tend to have dusky blotches, but not regular banding (see starry flounder). This species has an angular caudal fin with the longest rays at the center. The lateral line is nearly straight with a low arch over the pectoral fin. There is no accessory dorsal branch, but an anterior branch runs almost to the rear edge of the upper eye. Flathead sole have a medium to large mouth with one row of sharp conical teeth in both jaws. The maxillary extends to below the middle of the lower eye. The eyes are large with a narrow ridge and 1 – 2 rows of scales between them. This species has a strong anal spine. Pores are present below and behind the lower eye, but may be hard to see. The flathead sole is very similar to the petrale sole, but the upper jaw of the petrale sole has two rows of teeth and the lower jaw has a rounded rear ridge.
