Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 8; Dorsal soft rays (total): 8; Anal spines: 3; Anal soft rays: 5. Diagnosis: Underside of mandible with numerous tiny pores, no ridges. Preocular spine usually simple, and flattened anteriorly and posteriorly; supraocular spines occurring only posterior to vertical midline of eye; no additional spines between lacrimal and suborbital ridges; upper opercular spine simple. Midinterorbital space covered with scales; interorbital space shallow, becoming shallower with growth. Pored lateral-line scales 34-36 (mode 35); longitudinal scale rows 57-63 (57). Pectoral-fin rays 20-22 (21); pectoral fin short (2.9-3.5, mean 3.2 in SL), not reaching a vertical at origin of last dorsal-fin spine. Posterior margin of maxilla not reaching a vertical at posterior margin of pupil. Snout length long (3.5-4.0, 3.7 in HL); interorbital width wide (5.2-6.7, 5.7 in HL); body depth shallow (2.8-3.4, 3.1 in SL). Bilobed portion of swimbladder less than half of total swimbladder length. There are no distinct small black spots on head or lateral line (Ref. 54394).
Found on the continental shelf and continental slope (Ref. 75154). Most specimens taken in trawls have sand grains inside the mouth indicating occurrence on open, predominantly sandy substrata (Ref. 54394).
