Bassozetus zenkevitchi Rass, 1955 .

To 30.9 cm (12.2 in) TL (Hanke et al. 2015). Pacific coast of Honshu, Japan (Machida and Tachibana 1986), to south-eastern Kamchatka (Sheiko and Fedorov 2000); two records from south-eastern Bering Sea, Alaska at 56°N, 169°05’W (Orr et al. 2005) and 56°01’N, 168°55’W (Hoff 2013), to southwest of Hesquiat Peninsula (49°N, 127°18’W), Vancouver Island (Hanke et al. 2015). Depth: 200 to perhaps 2,620 m (656–8,954 ft) (min.: Sheiko and Fedorov 2000; max.: Machida and Tachibana 1986). A maximum depth of 6,930 m (22,730 ft) (Nielsen and Merrett 2000) is considered unlikely [see explanation in Fujii et al. 2010].
