(Bathypolypus bairdii)

Almennt

Skrokkur nokkuð kantaður og þakinn smágerðum vörtum. Höfuðið álíka breitt og bolurinn.  Er mjög áþekk Bathypolypus arcticus og álíka að stærð. Tegundin er útbreidd í N-Atlantshafi; finnst suður og vestur af landinu en ekki í svalsjónum undan Norðaustur og Austurlandi. Tegundin er botnlæg, en lífshættir eru lítt þekktir.  Kvendýr og ungviði eru nauðalík tegundinni Bathypolypus arcticus. Karldýr B. bairdii eru auðgreind á þverstýfðum kólfi á æxlunararmi með 10 til 16 blöðkum, en í B.arcticus er hann oddmjór í endann, með 8 til 10 blöðkum.

Bathypolypus bairdii (Verrill, 1873)

The largest confirmed mantle length is about 75 mm, but clearly it may attain larger sizes. The distribution is in low Arctic and North Atlantic wates. In the vicinity of Iceland, it is the most common the Boreal and Boreal-Arctic waters. B. bairdii is mostly confinded to the shelfs and the upper slopes, but has been collected at 1600 m. It is by far the most abundant bottom cephalopod of the Boreal Atlantic. Biology is little known, and it is often mistaken for B. arcticus.
