Short description
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 0; Radios blandos dorsales (total) : 109 - 117; Espinas anales: 0; Radios blandos anales: 86 - 90. Body completely covered with small, imbricate, cycloid scales; barbels present on snout (6) and chin (6); branchiostegal rays 8; median basibranchial tooth patch absent; developed gill rakers on first arch 4 or fewer; pelvic fin rays inserted at about level of preopercle, well behind eye (Ref. 34024). Ventral fins dark, gradually becoming darker at the extreme blackish edge (Ref. 13608).
Body shape (shape guide): elongated.
Common species (Ref. 34024). Adults benthopelagic (Ref. 34024) down to 650 m, but most often on the continental shelf (Ref. 3686), on sandy and muddy bottoms (Ref. 2683). Juveniles common in reefs (Ref. 34024). Smaller silvery specimens taken far out at sea in the epipelagic (Ref. 34024). Oviparous, with oval pelagic eggs floating in a gelatinous mass (Ref. 205).
