Etymology: Allocyttus: Greek, allos = other + Greek, kyttaros, kytos = a convex cavity.
Environment / Climate / Range
Marine; bathypelagic; oceanodromous (Ref. 51243); depth range 560 - 1300 m (Ref. 6390). Deep-water; 43°S - 55°S
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 36 - ? cm
Max length : 47.0 cm TL male/unsexed; (Ref. 6390); common length : 35.0 cm TL male/unsexed; (Ref. 9258); max. published weight: 1.5 kg (Ref. 6390); max. reported age: 100 years (Ref. 27140)
Southwest Pacific: New Zealand and Australian waters south of 43°S (Ref. 27159). Also Ref. 26139.
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).
Displays seasonally synchronised reproduction.
