Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Ραχιαίες άκανθες (συνολικά) : 0; Μαλακές ραχιαίες ακτίνες (συνολικά) : 108 - 118; Εδρικές άκανθες: 0; Μαλακές εδρικές ακτίνες: 78 - 89; Σπόνδυλοι: 55 - 56. 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).
Adults benthopelagic to 650 m depth, juveniles common on reefs (Ref. 34024). At depths of about 40-75 m, adults are found deep on mud and broken shell bottom (Ref. 36413). Smaller silvery specimens taken far out at sea in the epipelagic (Ref. 34024). Caught occasionally (Ref. 34024). Oviparous, with late post-flexion and transformation stage larvae found in midwater (Ref. 36413). Oval, pelagic eggs float in a gelatinous mass (Ref. 205).
Oviparous, with no specialized copulatory organ (Ref. 36413).
