Short description
Hình thái học | Sinh trắc học
Các tia vây lưng cứng (tổng cộng): 2; Tia cứng vây hậu môn 0. Head short, its underside moderately to extensively scaled, but sometimes only a file or narrow band of small scales is present below the suborbital and preopercular ridges and posteriorly on lower jaw. Eyes relatively large. Snout short, moderately pointed, with small naked patches on dorsal surface behind leading edges. Pyloric caeca 13 to 21. Overall color is medium brown to somewhat straw color; fins darker, blackish in some; the dorsal and pelvic fins darker distally; oral cavity lining dark gray or brown.
A benthic species found on the continental slope (Ref. 75154). This species is being imported and sold to the United States by the Argentines under the name grenadero (Ref. 5171).
