Longitud en la primera madurez / Tamaño / Peso / Edad
Madurez: Lm 42.0, range 41 - 43 cm
Max length : 75.0 cm SL macho / no sexado; (Ref. 5208); peso máximo publicado: 3.3 kg (Ref. 128737); peso máximo publicado: 3.3 kg; edad máxima reportada: 44 años (Ref. 128738)
Espinas dorsales (total) : 0; Radios blandos dorsales (total) : 55 - 61; Espinas anales: 0; Radios blandos anales: 36 - 44; Vértebra: 57 - 60. Blue-grey to blackish (Ref. 6606).
Body shape (shape guide): elongated; Cross section: oval.
Found on the continental slope and upper rise (Ref. 6606). Epibenthic (Ref. 58426) and benthopelagic (Ref. 5951). Deep waters to 3277 m (Ref. 58426). May move offshore with age and spawn in the deep parts of its range. Off the eastern coast of United States, it is speculated that the population use the area only as feeding grounds with spawning taking place to the north. Feed on benthic invertebrates (Ref. 9319). Maximum weight of female from Ref. 128738.
