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).

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.
