Adults feed on fishes and mysids, Crangon antarcticus and Chorismus antarcticus (Ref. 5192). Spawning from end of summer to early winter and hatching occurs throughout winter. Eggs large, 2.4-3.4 mm in diameter, bright red and benthic (Ref. 5192). Synchronous spawner (Ref. 50743). Larval pelagic phase is long (Ref. 35742).
吃魚與糠蝦， Crangon antarcticus 與 Chorismus antarcticus 。 (參考文獻 5192) 從夏天的末端到初冬與孵化產卵在冬天各處發生。 卵大的,2.4-3.4 mm 直徑, 鮮紅色與底棲的.(參考文獻 5192) 同步的產卵魚.(參考文獻 50743)
Oocyte maturation occurs synchronously, thus, spawning is completed in a single occasion (Ref. 50743).南極海: 南喬治亞州與三明治島的島大陸棚。
