Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Northeast Atlantic: Norwegian coasts to Namdahl to off Denmark, around British Isles and across to Iceland. Pelagic larvae spreading to western Murman and Icelandic waters.

Biology     Glossary (e.g. epibenthic)

Found on hard bottoms (gravel or shells) or among algae with temperatures ranging below 0°C. Feeds on small crustaceans (amphipods, decapods) and fishes. Spawns in early spring. Eggs demersal, in clumps on bottom, diameter 2 mm; larvae pelagic (Ref. 4698).
