Stenotomus porgies have deep and compressed bodies. The dorsal profile of the head is steep, the head is not very deep below the eye. The margin of the preoperculum is smooth. The small mouth opens at the front and the preorbital bone overlaps with the rear of the maxilla. The teeth in the front of the jaws are highly flattened incisors, thinner at the base and at the tips. There are rows of molars at the sides of the jaws. The dorsal fin contains 13 spines with the 1st spine being recumbent and the anal fin contains 3 spines. The pectoral fin is long and the caudal fin is forked. There are scales on the cheeks and the operculum, although there are no scales at the front of the head.[7] The largest species is the scup with a maximum published total length of 46 cm (18 in), while the longspine porgy has a maximum published total length of 30 cm (12 in).[6]
