Range : This species has a wide distribution, having been recorded from the 

 Kara sea region^ westward to Lille Karajok fjord, West Greenland. It lives in 

 depths from a couple of fathoms down to about 500 fathoms, more frequently in 

 temperatures above zero but also in temperatures down to at least 0-6.

 poda labelled " Greenland," but without specific locality. East Greenland, lat.
