دريايي موجوداتی که در محدوده وسیعی از آبهای آزاد از نزدیک بستر و یا روی کف بستر، در قسمت های میان آبی تا سطح آب و در برخی گونه ها با قابلیت پرواز، زندگی و تغذیه می کنند.; غير مهاجر; تغييرات عمق 1 - 440 m (Ref. 57178), usually 15 - 200 m. Temperate; 66°N - 28°N, 13°W - 36°E
Northeastern Atlantic: Trondheim Fjord and the Faeroe Islands to Portugal and along the Atlantic coast of Morocco (Ref. 1371). Not present in the Mediterranean (Ref. 90172).
Length at first maturity / Size / Weight / سن
Maturity: Lm 13.3, range 10 - 26 cm
Max length : 40.0 cm TL جنس نر / بدون خواص جنسي; (Ref. 1371); common length : 20.0 cm TL جنس نر / بدون خواص جنسي; (Ref. 4645); بيشينه سن گزارش شده: 5 سال ها (Ref. 72488)
خارهاي باله پشتي (کل) : 0; خارهاي باله مخرجي: 0. Chin barbel well developed. Body brownish yellow dorsally, becoming paler ventrally; a dark blotch is at the base of the pectoral fin.
Occurs mostly from 15 to 200 m in the Atlantic on muddy or sandy bottoms. Feeds on crustaceans, small fish, and polychaetes (Ref. 1371). Used in the production of fish meal, and in southern Europe as a human food (Ref. 35388).
Oviparous, sexes are separate (Ref. 205).
