Cosmopolitan; primarily in high latitudes in northern and southern hemispheres; polar basins southward to Beaufort Sea of Alaska and western Canada (Mecklenburg et al. 2011), to Chukchi Borderland (Meckleburg and Steinke 2015); also southern Sea of Okhotsk and Pacific coast of northern Japan (Hatooka et al. in Nakabo 2002) to Navarin Canyon, northern Bering Sea (Ebert 2003, Stevenson 2004), and Aleutian Islands (Personal communication: University of Washington, Burke Museum of Natural History and Culture Fish Collection, Seattle, Washington) to northern British Columbia (Love et al. 2005), to central Panama, including Gulf of California (Zorzi and Anderson 1988).
