Max length : 55.5 cm TL macho/indeterminado; (Ref. 106276); common length : 22.0 cm TL macho/indeterminado; (Ref. 1371); peso máx. Publicado: 830.00 g (Ref. 40637); Idade máx. registada: 20 anos (Ref. 1371)
Espinhos dorsais (total) : 0; Raios dorsais moles (total) : 24 - 28; Raios anais moles: 33 - 39. Dorsal fins widely spaced, interspace between second and third fins longer than base length of first dorsal fin. Lateral line continuous over whole body. Color is blue-gray dorsally, grading to white ventrally. Sometimes with a small black blotch at the base of the pectoral fin.
Body shape (shape guide): elongated; Cross section: circular.
Found over the continental slope and shelf to more than 1000 m, but more common at 300-400 m. Feeds mostly on small crustaceans but large individuals also prey on small fish and cephalopods. Makes daily vertical migrations: surface waters at night and near the bottom during the day. Sold fresh and frozen, and also processed as oil and fishmeal (Ref. 1371).
Oviparous and gonochorous (Ref. 205).
