Short description

Dorsal spines (total): 0; Dorsal soft rays (total): 14-16; Anal spines: 0; Anal soft rays: 19 - 22

Biology     Glossary (e.g. epibenthic)

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.

IUCN Red List Status (Ref. 115185)

Threat to humans
