Etymology: Neocyttus: Greek, neos = new + Greek, kyttaros, kytos = a convex cavity.
Ambiente: milieu / zona climatica / distribuzione batimetrica / gamma di distribuzione
Ecologia
marino batipelagico; oceanodromo (Ref. 51243); distribuzione batimetrica 200 - 1240 m (Ref. 6390), usually 450 - 800 m (Ref. 30191). Deep-water; 23°S - 48°S, 81°W - 176°W
Southeast Atlantic: off Walvis Bay, Namibia to Cape Province, South Africa. Southwest Atlantic: off Argentina. Eastern Indian Ocean: southern Australia, from about 26°S in Western Australia to Broken Bay (Ref. 7300), New South Wales. Southwest Pacific: New Zealand.
Lunghezza alla prima maturità / Dimensione / Peso / Età
Maturità: Lm 34.0, range 29 - ? cm
Max length : 40.0 cm SL maschio/sesso non determinato; (Ref. 30191); peso massimo pubblicato: 2.0 kg (Ref. 6390); Età massima riportata: 100 anni (Ref. 27140)
Spine dorsali (totale) : 7; Raggi dorsali molli (totale) : 33 - 35; Spine anali: 3 - 4; Raggi anali molli: 30 - 33. Body grey, fins dark (Ref. 6548).
Body shape (shape guide): short and / or deep; Cross section: compressed.
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).
