Remarks Cool-water, anti-tropical distribution, at latitudes greater than 15° (Ref. 92949). Oceanic and can live at great depths (Ref. 2850), but occasionally cast up on beaches (Ref. 9563). Large adults sometimes kill themselves by swimming out of the water onto beaches; occurrence of such strandings may be linked to certain areas, seasons or months and often in spates (Ref. 92949). Feed on euphausiid crustaceans, small fishes and squid (Ref. 6738); Euphausiidae being their main diet but possibly feed only when highly concentrated in areas of upwelling. With few predators and parasites; adaptative significance of autotomy still unknown. Occassionally associate in pairs (gender undocumented) but no record of group larger than three or of schooling behavior (Ref. 92949). Spawning occurs between July and December and larvae are encountered near the surface (Ref. 9337). Spawns in the North Atlantic along the west coast of Florida and off the northern coast of America; in or near the Straits of Messina in the Mediterranean; in the South Pacific in the Catham Rise area of New Zealand and somewhere off the west coast of southern Australia (Ref. 92949).
