Grootte / Gewicht / Leeftijd
Maturity: Lm ?  range ? - ? cm
Max length : 75.0 cm TL mannelijk / geslacht onbekend; (Ref. 2850); max. gepubliceerd gewicht: 2.1 kg (Ref. 56581); max. gerapporteerde leeftijd: 20 Jaren (Ref. 56581)
Dorsale stekels (totaal) : 0; Dorsale zachte stralen (totaal) : 54 - 60; Anale stekels: 0; Anale zachte stralen: 39 - 42. Head short; snout pointed; chin barbel short. Color variable from pale but definite blue gray or olive green throughout to deep violet or blue black; darker on outer edges of fins and very dark on edge of caudal and fins on ventral part of body; dark on lower part of gill cover and branchiostegals (Ref. 6885).
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).
