Remarks. This species is a bathypelagic form widely distributed in nearly all the oceans of the world. It was first recorded from the Antarctic and was for a long time regarded as essentially a southern form, but it has now been recorded from all the oceans of the world except the North Atlantic, the Arctic Ocean and the Mediterranean. It has most frequently been recorded from the tropical and sub-tropical waters of the Atlantic and Pacific, but also as far north as the Behring Sea, the coasts of Japan and the coasts of California, and as far south as Graham Land and the Ice Edge in the Bellingshausen Sea (Tattersall 1955, San Vicente 2010a).
