Rem.: epi-mesopelagic.
Sampling depth (sub-Antarct.) : 0-2500 m. Sargasso Sea: 500-1000 m ( Deevey & Brooks, 1977, Station "S");;
According to Østvedt (1955) this species has not previously been repôrted from the Norwegian Sea.
See remark in Scolecithrix dubia.
For Mazzocchi & al. (1995) most of the females collected lacked a P5 (careful examination of the specimens gave no sign of the presence of this leg). Noted also by Campaner (1984) in the material from epipelagic waters off Southern Brazil.
After Benedetti & al. (2018, p.1, Fig.2) this species belonging to the functional group 5 corresponding to small sac-spawning detritivorous.
