Short description
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 10 - 11; Mjukstrålar i ryggfenan (totalt) : 23 - 26; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 23 - 26. Caudal fin small. Lower 7-8 rays of pectoral fins moderately exserted but not especially thickened.
Found on mud bottoms with some rocks (Ref. 4698). Maximum depth reported at 930 m (58426). Benthic to epibenthic (Ref. 58426). Feeds on small crustaceans, usually amphipods and mysids, rarely polychaetes and fishes (Ref. 4698).
