Morphology | Morphometrics
soft rays: 29 - 33. Scales absent from a median band anterior to the dorsal fin and from the musculature at the base of caudal fin. Belly scales loosely arranged, not in chevrons. Vertebrae 65-75. Margins of dorsal and anal fins straight with rays of equal length. Lateral line pores linearly arranged along the unbranched canals.
Northeast Atlantic: 74°N (Novaya Zemlya and Bear Islands) to 49°N (Channel Islands, western English Channel), including eastern Greenland, Iceland, Barents Sea (but not the White Sea) and the Baltic (but not the Gulf of Bothnia and Finland).
This schooling species is usually territorial and burrowing (Ref. 40). Feed on plankton. High activity is correlated to periods with strong tidal currents; then they leave their bottom hides and form large shoals. During low light intensity (night and winter) they bury in the bottom (Ref. 35388).
