Descripción breve
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 7 - 8; Radios blandos dorsales (total) : 19 - 21; Espinas anales: 0; Radios blandos anales: 14 - 15. Spinous dorsal short with anterior spines longest; caudal slightly rounded; pectorals rounded, lower 8 rays exserted, middle rays lengthened reaching anal insertion; pelvic fins reaching anus (Ref. 6885). Color pale brown, lighter ventrally; dark band through eye; eye and cirrus black; dorsal fins speckled, with spinous fin darker; usually 4 dark saddles across back, and dark band at base of caudal fin; posterior edge of caudal darker (Ref. 6885). Recognizable by having a combination of gill membranes fused to isthmus, strong longitudinal depression in occiput, scales embedded in papillae covering body except in axilla, moderate-sized spinous dorsal, second dorsal with fewer than 22 rays, and a black band through eye (Ref. 6885).
Body shape (shape guide): fusiform / normal.
Occurs near shore and to 73 m depth, on sand and rock bottoms and shallow exposed areas (Ref. 2850).
