Maturity: Lm 28.2, range 28 - 30 cm
Max length : 91.5 cm TL mannelijk / geslacht onbekend; (Ref. 106276); common length : 23.5 cm TL mannelijk / geslacht onbekend; (Ref. 1371); max. gepubliceerd gewicht: 3.1 kg (Ref. 40637); max. gerapporteerde leeftijd: 20 Jaren (Ref. 35388)
Dorsale stekels (totaal) : 0; Dorsale zachte stralen (totaal) : 30 - 40; Anale zachte stralen: 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).
