Udbredelse. 



Ophiopholis aculeata er en af de veil de norske Kyster 

 hyppigst forekommende Ophiurider, især skal den ifølge 

 M. Sårs være talrig ved Finmarken og Nordland. Den 

 gaar fra Litoralbæltet ned til 300 Favnes Dyb, i størst 

 Mængde optræder den dog imellem Laminarierodderne. 



Arten er endvidere kjendt fra Karahavet og den 

 kariske Port (Stnxherg, 35 Fv., Levinsen, 12 — 75 Fv.); 

 Barentshavet (Marenzeller, 50 Fv., Hoffmann, 5 — 220 Fv.); 

 Spitsbergen (Liltken); Jan Mayen, 25 — 90 Fv. (Fischer); 

 Island, Færøerne, Færøkanalen, 53 — 560 Fv. (Lyman, 

 Hoyle); de britiske Kyster, — 400 Fv. (Norman m. fl.), 

 hvor den ligesom ved den norske Kyst tiltager i Hyppig- 

 hed mod Nord ; de tyske og danske Nordsøkyster, Skagerak, 

 Kattegat, 6 — 24 Fv. (Petersen) ; Øresund (Liitken) ; Store 

 og Lille Belt, Sveriges Vestkyst indtil Kullen (Ljungman); 

 Grønland (Liltken, Duncan & Sladen) ; Nordamerikas Nord- 

 og Østkyst indtil Cape Hatteras, 13—1000 Fv. (Lyman, 

 Verrill, Murdoch) og Beringsstrædet (Ludwig). Den synes 

 saaledes at være en circumpolar Form.

Distribution. 



Ophiopholis aculeata is one of the Opbiurideans most 

 frequently met with on the Norwegian coast; according 

 to M. Sårs, it is especially abundant in Finmark and 

 Nordland. It passes from the littoral belt down to 300 

 fathoms deep. It appears most abundantly, however, 

 between the laminaria-roots. 



The species is known, further, from the Kara Sea 

 and the Strait of Kara (Stuxberg, 35 fath.. Levinsen, 

 12 — 75 fath.) ; the Barents Sea (Marenzeller, 50 fath., 

 Hoffmann, 5 — 220 fath.); Spitzbergen (Liitken); Jan Mayen, 

 25 — 90 fath. (Fischer); Iceland, the Færo islands, the 

 Færo channel, 53 — 560 fath. (Lyman, Hoyle) ; the British 

 coasts, — 400 fath. (Norman and others), where it, like as 

 on the Norwegian coast, becomes more abundant towards 

 the north; the German and Danish North Sea coasts, the 

 Skager Rack, Cattegat, 6 — 24 fath. (Petersen) ; Øresund 

 (Liitken) ; the Great and Little Belt, west coast of Sweden, 

 as far as Kullen (Ljungman); Greenland (Liitken, Duncan 

 & Sladen); the north and east coasts of North America, 

 as far as Cape Hatteras, 13 — 1000 fath. (Lyman, Verrill, 

 Murdoch) and the Behrings straits (Ludwig). It appears 

 therefore to be a circumpolar form.
