Inhabits the lower regions of the continental slope between 800 m and 1, 800 m. It appears that sex segregation is also basic to this species, but whether or not the species migrates extensively or uses the North American west coast slopes only as feeding areas is not known (Ref. 1371). Benthopelagic (Ref. 58302). Feeds on benthic invertebrates (Ref. 9319). Taken frequently by deep slope water trawlers fishing for Microstomus pacificus and deepwater Sebastes species (Ref. 1371).
栖息于在 800 公尺与 1,800 公尺之间的大陆斜坡的下面区域。 它出现性别分离对这种也是基本的, 但是否此鱼种广泛地移动或者使用，北美西岸斜坡只当作，摄取食物的区域不为人所知。 (参考文献 1371) 吃底栖的无脊椎动物。 (参考文献 9319) 为 Microstomus pacificus 与深水的 Sebastes 种时常捕获用深的斜坡水底拖网了。 (参考文献 1371)
