A nearshore benthic species usually abundant in shelf waters of East Antartica (Ref. 122792). Adults feed primarily on amphipods, other fishes, and molluscan larvae, with lesser amount of polychaetes and mysids. They capture some prey in the water column, but are not cryopelagic.
主要吃片腳類動物，其他的魚與軟體動物的幼生,與比較少量的多毛類動物與糠蝦。 在水團捕獲一些獵物, 但是不是寒帶大洋性。
