Short description

Dorsal spines (total): 7 - 9; Dorsal soft rays (total): 26-33; Anal spines: 2-3; Anal soft rays: 22 - 28. Head broad and depressed. First dorsal fin with short but strong isolated spines, not connected by a membrane. Caudal fin lunate in adults, upper lobe longer than lower. Back and sides dark brown, with 2 sharply defined narrow silvery bands.

Adults occur in a variety of habitats, over mud, sand and gravel bottoms; over coral reefs, off rocky shores (Ref. 10948) and in mangrove sloughs; inshore around pilings and buoys, and offshore around drifting and stationary objects; occasionally in estuaries (Ref. 9739). Form small groups and may pursue small pelagic inshore (Ref. 48635). Feed on crabs, fishes, and squids (Ref. 5213, 10948, 13442). Form spawning aggregations during the warm months in the western Atlantic; eggs and larvae planktonic (Ref. 12459). Caught in small quantities due to its solitary behavior (Ref. 9626). Good food fish; marketed fresh (Ref. 5284), smoked, and frozen (Ref. 9987). Also caught for sport (Ref. 26938).

IUCN Red List Status (Ref. 115185)
