Biology     Glossary (e.g. epibenthic)

Oceanic, found to depths of at least 1,524 m. Migrate in the water column at depths of 150-250 m during the day and to about 50 m at night (Ref. 57912). Mesopelagic (Ref. 5951). A cyclic selective feeder of copepods and euphausiids (Ref. 4739). They become sexually mature when 1 year old. Spawning takes place in March - September, producing 200-500 eggs, floating on the surface (Ref. 35388). Lipid content is 5.5 % in fresh body weight and wax ester is 15.3 % in total lipids (Ref. 8966).
