Max length : 40.0 cm SL hane/ej könsbestämd; (Ref. 30191); publicerad maxvikt: 2.0 kg (Ref. 6390); rapporterad maxålder: 100 år (Ref. 27140)
Taggstrålar i ryggfenan (totalt) : 7; Mjukstrålar i ryggfenan (totalt) : 33 - 35; Taggstrålar i analfenan: 3 - 4; Mjukstrålar i analfenan: 30 - 33. Body grey, fins dark (Ref. 6548).
Inhabit continental slopes (Ref. 9563), forming large shoals over rough ground near pinnacles and canyons (Ref. 6390). Juveniles are pelagic and tend to be dispersed over smooth grounds (Ref. 6390). Feed on salps, fish, crustaceans and squid (Ref. 27230). Eggs float near the surface and larvae also inhabit surface waters (Ref. 6390).
