Nota: In this chart the area frequented by whaling vessels has been hatched. The Antarctic circle (66°.5 S) has been drawn as a broken line. The numbers I to VI refer to the sectors into which the Antarctic seas are divided according to Mackintosh (1942) (after Vervoort, 1951).

Remarks

epipelagic -?. Sampling depth (Antarct., sub-Antarct.) : 0-600 m.
Observed by Dias & al. (2010)) in Intermediate Antarctic water (Brazil).
After Arashkevich (1978) the diets of the species are pennate diatoms (mainly in the gut content), and mess frequent: centric diatoms, flagellates, tintinnids, crustacea, shapeless mass.
