Sargasso Sea: 0-1000 m (Deevey & Brooks, 1977, Station "S");
For Østvedt (1955) it is probably only an exceptional circumstance that this species penetrates as far into the Norwegian Sea as latitude 66° N.
Vervoort (1965, p.36, 37) does not share the opinion of Brodsky (1950) concerning the identification of the female of Tanaka (1937). For Vervoort (1965, p.37), the reference to this species in Canu (1886, Norman (1903), Cleve (1904 a), Pearson (1906), Farran (1908), Paulsen (1909), Stebbing (1910) and Wolfenden (1911) must be taken with some reserve as no descriptions are added to their records, so that other species may have been included. S. securifrons must be considered as a species from deep and intermediate water layers. For Owre & Foyo (1967, p.65) S. securifrons is grossly similar to S. corystes but larger.
Park (1983, p.205) notes the occurence of the species in the north of the Antarctic convergence, the southermost was between 46°40'S, 170°03'W.
For Schnack (1989) the Itoh's index value of the mandibular gnathobase = 552.
