Etymology: Allocyttus: Greek, allos = other + Greek, kyttaros, kytos = a convex cavity;  niger: niger refers to the blackish color of freshly caught specimens. It also reflects the common name "black oreo", which has been widely used in the New Zealand deepwater fishery for several years (Ref. 27159).

Biologi     Ordlista (t.ex. epibenthic)

Found close to the sea bed in deep water. Form large shoals over rough ground near pinnacles and canyons. Juveniles are pelagic and inhabit oceanic waters. They tend to be dispersed over smooth grounds (Ref. 6390). Feed mainly on salps and benthic crustaceans (Ref. 27150). Eggs float near the sea surface and larvae also inhabit surface waters (Ref. 6390). Based on trawl catch rates, there is no evidence of vertical migration during day or night (Ref. 27150).
