In the hatched regions the literature notes a common occurrence. off the west coast of Norway, and in the northern British waters; at the Faroe Islands it seems to be rare, while on the other hand it is one of the commonest species in Iceland waters, albeit lacking here along the north coast. About Greenland, Abietinaria filicula is very rare, and has only been recorded with certainty once from the west coast, near Godthaab. It belongs to the littoral region, but can quite exceptionally also move down into the abyssal, as for instance west of the Faroe Islands.
