Descrição suscinta
Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 66 - 72; Raios dorsais (total) : 0; Espinhos anais: 1; Raios anais : 45 - 50. Caudal fin narrow with oval free end; anal fin occasionally absent; pectorals large, bluntly pointed (Ref. 6885). Pale green on dorsal surface, cream ventrally; brown or green bars along midside and streaks or spots on upper part of sides; brown bars and dots on dorsal fin form bands parallel to fin margin and, on caudal fin, produce vertical bars; other fins pale; lining of mouth pale (Ref. 6885).
Found in shallow bays and offshore waters (Ref. 2850); on sand mixed with silt, pebbles, and stones to depths of 425; usually shallower than 200 meters (Ref. 51666). Sometimes takes hooks using marine worms as bait (Ref. 6885).
