Grootte / Gewicht / Leeftijd
Maturity: Lm ?  range ? - ? cm
Max length : 60.0 cm TL mannelijk / geslacht onbekend; (Ref. 41039)
Dorsale stekels (totaal) : 1; Dorsale zachte stralen (totaal) : 10 - 12. Body white to grey-brown in color, underside darker (Ref. 3974). Insertion of the pelvic fin only slightly anterior to the origin of the dorsal fin. Lacks scale on the opercle (Ref. 37108).
Occurs on the middle and lower slope primarily above the 4°C isotherm. Hovers within a few meters of substrate, parallel to it or inclined at varying angles (Ref. 6727). Feeds on polychaetes, pelecypods, amphipods and other benthic prey (Ref. 6727).
