Etymology: Neocyttus: Greek, neos = new + Greek, kyttaros, kytos = a convex cavity.
Environment: milieu / climate zone / depth range / distribution range
Marine; bathypelagic; oceanodromous (Ref. 51243); depth range 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.
Length at first maturity / Size / Weight / Age
Maturity: Lm 34.0, range 29 - ? cm
Max length : 40.0 cm SL male/unsexed; (Ref. 30191); max. published weight: 2.0 kg (Ref. 6390); max. reported age: 100 years (Ref. 27140)
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).
