دريايي; لب شور 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.; اقیانوس رو (Ref. 51243); تغييرات عمق 10 - 200 m (Ref. 1371), usually 30 - 100 m (Ref. 1371). Temperate; 72°N - 35°N, 27°W - 42°E
Northeast Atlantic: southeastern Barents Sea and Iceland to Portugal, also in the Black Sea, Aegean Sea, Adriatic Sea and adjacent areas. Rare in the northwestern Mediterranean.

Maturity: Lm 28.2, range 28 - 30 cm
Max length : 91.5 cm TL جنس نر / بدون خواص جنسي; (Ref. 106276); common length : 23.5 cm TL جنس نر / بدون خواص جنسي; (Ref. 1371); بيشينه وزن گزارش شده: 3.1 kg (Ref. 40637); بيشينه سن گزارش شده: 20 سال ها (Ref. 35388)
خارهاي باله پشتي (کل) : 0; شعاع نرم باله پشتي (کل) : 30 - 40; شعاع نرم باله مخرجي: 30 - 35. Body elongate; head small. Chin barbel small or absent. Lateral-line canals on head with pores. Color is variable; yellowish-brown, dark blue or green, sides yellowish grey, white and silvery on belly; often with a small dark blotch at the upper base of the pectoral fin.
More commonly found from 30 to 100 m, mainly on mud and gravel bottoms, but also on sand and rock. Feed on shrimps, crabs, mollusks, small fish, polychaetes and cephalopods. Migrate to the open sea only after the first year of life. Eggs are pelagic. Larvae and juveniles are associated with jellyfish. Upon maturity, small chin barbel characteristic of juveniles disappear (Ref. 53061). Spawn in batches (Ref. 51846). Utilized fresh, dried or salted, smoked and frozen; eaten steamed, broiled and baked (Ref. 9988).
Oviparous, sexes are separate (Ref. 205).
