Descripción breve
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 8; Radios blandos dorsales (total) : 9; Espinas anales: 2; Radios blandos anales: 8. Characterized by having dorsal fin rays VII-I, 9; anal fin rays II,8; pectoral fin rays 13; pelvic fin rays I, 5; pored lateral line scales 24; predorsal scales 3-4; circumpeduncular scales 12 (Ref. 93839); color is coppery or silvery with saddle or bar across the caudal peduncle and a wedge-shaped bar below the eye. Similar to A. fuscus but usually has fewer gill rakers (25-27 versus 28-30). Leading edge of ventral fin clearly pale-blue (Ref. 48635); characterized further by grey caudal peduncle with broad dark bar at base; pale grey at night; greatest depth of body 2.2-2.6 in SL (Ref. 90102).
Body shape (shape guide): short and / or deep; Cross section: compressed.
Occur in outer reef slopes generally at depths below 30 m (Ref. 1602). Nocturnal species (Ref. 7300). Solitary or in small groups (Ref 90102).
