морской демерсальный; мигрирует в океане (Ref. 51243); пределы глубины 1 - 1010 m (Ref. 114491). Polar; 45°S - 78°S, 180°W - 180°E
Circumpolar south of Antarctic Polar Front, but not found in Ross Sea; adults only in higher latitudes (South Orkneys, South Shetlands, Peter Island) and south of the Weddell-Scotia confluence, but adults and juveniles in the region of South Sandwich I, South Georgia and Bouvet. Reported from off the Cape, South Africa and from 43°17'S, 48°55'E (Ref. 4066).

Max length : 11.5 cm SL самец/пол неопределен; (Ref. 114491); 10.3 cm SL (female); наибольший вес (опубликованные данные): 15.00 g (Ref. 124149); наибольший возраст (опубликованны данные): 4 годы (Ref. 94119)
колючие лучи спинного плавника (общее число) : 0; членистые (мягкие) лучи спинного плавника (общее число) : 14 - 16; колючие лучи анального плавника: 0; членистые (мягкие) лучи анального плавника: 19 - 22.
Oceanic and mesopelagic, found in the upper 100 m south of the Antarctic Polar Front but deeper northwards (Ref. 4066). Adults take more euphausiids and also prey upon polychaetes. The diet of juveniles of less than 6 cm SL consists mainly of copepods, with some euphausiids and hyperiids. Possibly the most common myctophid occurring south of the Antarctic Polar Front.
