Etymology: Gymnoscopelus: Greek, gymnos = naked + Greek, skopelos, a lantern fish (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; benthopelagic; oceanodromous (Ref. 51243). Temperate; 19°S - 62°S, 70°W - 180°E
Generally ranges between the Subtropical Convergence and the Antarctic Polar Front (Atlantic Sector to south of Australia/New Zealand), but with northern extensions in eastern boundary currents; absent in the sub-Antarctic region of the Pacific. There is a beach-washed specimen from Port Alfred, South Africa (Ref. 4066). Also found in Argentina (Ref. 86326) and Uruguay (Ref. 54736).
