Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 10 - 11; Raggi dorsali molli (totale) : 23 - 26; Spine anali: 0; Raggi anali molli: 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).
