Spine dorsali (totale): 12 - 13; Raggi dorsali molli (totale): 10-11; Spine anali 3; Raggi anali molli: 8. Snout short, lower jaw slightly projecting. Mouth small. Pectoral fins relatively short, not reaching level of anus. Scale rows on back rising obliquely above lateral line. Back and upper sides vermilion, shading to silvery with reddish tinge ventrally, with narrow horizontal yellow lines below the lateral line. The dorsal and caudal fins yellowish; the anal and pelvic fins whitish.
Adults are found in moderately deep waters, most common over rock, gravel or sand bottoms near the edge of the continental and island shelves, often in large schools. Young fish occur in shallower depths (below 25 m), also often forming large schools. They feed on fishes, shrimps, crabs, polychaetes, other benthic invertebrates, cephalopods and planktonic organisms. Good food fish (Ref. 9626).
Spawning occurs over most of the year with peak activity during spring and summer, at least in the northern part of the range (Puerto Rico to the Carolinas).
