Considered as vertical migrator.
Sampling depth (sub-Antarct.): 0-750 m. Sargasso Sea: 0-1500 m (Deevey & Brooks, 1977, station "S"). 298-526 m at Station N-1 (SW Bösö, E middle Japan) from Furuhashi (1966 a). 390-400 m (Pipe & Coombs, 1980 at 60°N, 07°W).
For Vervoort (1957, p.71) this species occurs from South of Tasmania (44°05'S, 147°35'E), far to the North of the Antarctic convergence, mainly restricted to moderately deep water layers, occasionally penetrating into deeper waters; at the surface the species is sometimes found in appreciable quantities, especially during the night.
Timonin (1971, p.282) considers the trophic interrelations in the equatorial and tropical Indian Ocean, and divides the plankters into 6 trophic groups from the litterature and the results of studies of mouth-parts structure and intestine content. This species is omnivorous.
After Sano & al. (2013, p.14, Table 2) atomic C:N ratio (mean ±SD) = 5.5 ±0.7, n =8.
