📖 Overview

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 . Benthopelagic . Feeds on benthic invertebrates . Taken frequently by deep slope water trawlers fishing for Microstomus pacificus and deepwater Sebastes species .
