Remarks: This is one of the most common species of Scina in Antarctic waters, ranging from the Antarctic Convergence to the Antarctic Continent. Most records are from depths of 1000–2000 m to the surface. The above records provide range extensions for the Antarctic Zone of the Southwest Atlantic (mainly) and the Pacific and Eastern Indian Ocean Sectors. I could not find any previous records for the Southeast Pacific Sector, thus they are new records for that region, confirming the circumpolar distribution of this species.
