Small head and mouth. Body is oval. Skin is marbled and smooth. Lateral line almost straight, slight curve above the pectoral fin (Ref. 35388).
Body shape (shape guide): short and / or deep.
Lives most often on stony bottoms. Feeds on a variety of small invertebrates, but polychaetes seem to dominate. Apparently they do not feed in wintertime (Ref. 9900). Marketed fresh and frozen; eaten steamed, fried, broiled, microwaved and baked (Ref. 9988).
Spawning is mainly confined to depths of 55-91 m in the northwestern North Sea and commences at a minimum temperature of 6.5 °C in Scottish waters. Sex ratio is about 1:1, but females progressively predominate upon sexual maturity.
