Ecologia
marino batidemersale; oceanodromo (Ref. 51243); distribuzione batimetrica 50 - 1000 m (Ref. 27121), usually 150 - 450 m (Ref. 27121). Deep-water; 11°S - 37°S, 5°E - 33°E (Ref. 58452)
Southeast Atlantic: Baie Farte, Angola around Cape to Natal, South Africa. Also found on Valdivia Bank (26°18'S, 6°20'E).
Lunghezza alla prima maturità / Dimensione / Peso / Età
Maturità: Lm 47.4  range ? - ? cm
Max length : 140 cm TL maschio/sesso non determinato; (Ref. 6605); common length : 50.0 cm TL maschio/sesso non determinato; (Ref. 1371)
Spine dorsali (totale) : 1; Raggi dorsali molli (totale) : 47 - 54; Spine anali: 0; Raggi anali molli: 37 - 41. Light brown above, silvery to white below (Ref. 6605).
Body shape (shape guide): elongated; Cross section: oval.
Found on the continental shelf and slope to depths over 1,000 m (Ref. 27121). Juveniles (to about 64 cm) feed on small crustaceans and small deep-sea fishes such as lanternfishes, whereas larger individuals feed chiefly on small hakes and jack mackerel (Ref. 1371); cannibalism is common (Ref. 27121). Migrates southward in the spring and northward in autumn (Ref. 1371). Breeds throughout the year, peaks of reproductive activity in August and September (Ref. 36731). Marketed smoked, frozen, and fresh on ice; eaten steamed, fried and baked (Ref. 9988).
