морской батидемерсальный; немигрирующий; пределы глубины 395 - 1700 m (Ref. 3587). Deep-water; 55°N - 27°S, 26°W - 36°E
Eastern Atlantic: Irish slope to Cape Verde, including the Mediterranean. Occurrence in southern Africa is based only on specimens from off Namibia and not 'west coast of South Africa' as reported by Iwamoto 1986 (Ref. 2800 in FishBase) (Ref. 11953).
Size / Вес / Возраст
Maturity: Lm ? range ? - ? cm
Max length : 60.0 cm TL самец/пол неопределен; (Ref. 11953); наибольший возраст (опубликованны данные): 11 годы (Ref. 58045)
Snout long, narrow, sharply pointed. Dorsal scute row striating from just behind the head and extending to about behind a vertical through the anus, with more than 20 scute. Ventral scute row not reaching anus. Scute keels generally smooth blade-like, without multicuspid tips in small individuals (<30 cm), becoming more multicuspid with size. Scales adherent; belly completely scaled.
Primarily a pelagic feeder, feeds primarily on pelagic copepods, but also takes mysids, shrimps, cephalopods, fish, polychaetes and gastropods (Ref. 1371). Mainly reduced to fishmeal and oil (Ref. 1371).
