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).

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).
发现在深水中接近海床。 形成大群鱼群在峰顶与峡谷附近的粗糙的底部之上。 稚鱼是大洋性的而且居住于大洋性水域。 他们倾向零零散散的在平滑的地面之上.(参考文献 6390) 主要捕食被囊动物与底栖的甲壳动物。 (参考文献 27150) 在海洋表面与仔鱼附近的卵漂流物也居住于水表面。 (参考文献 6390) 以拖网捕捉率为依据, 没有对于垂直性回游的证据在白天或夜晚.(参考文献 27150)
