Ekologi
marina pelagic-oceanic; djupintervall 25 - 1200 m (Ref. 106604). Deep-water; 40°N - 45°S
Western Atlantic: Virginia and Florida (USA), Uruguay and Argentina; reported off Suriname (Ref. 13608) and Brazil (Ref. 57911). Southeast Atlantic: off the eastern Cape and northern Natal in South Africa (Ref. 11228). Some reports of this species from the southeast Atlantic may be misidentifications of the recently described Etmopterus compagnoi (Ref. 36731).
