Épines dorsales (Total) : 0; Rayons mous dorsaux (Total) : 58 - 67; Épines anales: 0; Rayons mous anaux: 42 - 53; Vertèbres: 52 - 55. Eye large, its diameter about equal to snout length. Lower jaw slightly projecting; chin barbel absent. Elongate filament in first dorsal fin absent. Anal fin originating at about the midlength of body, deeply indented; pectoral fins not reaching to anal fin origin. Outer 2 pelvic rays elongate. Anterior gill rakers of 1st arch longer than gill filaments. Ventral light organ absent. Color is generally pale, silvery in fresh specimen; urobranchial cavity black (Refs. 1371, 43939).
Body shape (shape guide): elongated; Cross section: compressed.
Epibenthic (Ref. 58426). Food consists of free-living small animals, such as crustaceans and squids. This species is reportedly being caught by trawl in temperate waters of Australia (Ref. 9563).
