Deepwater Cutthroat Eel. To 137 cm ( 54 in ) TL (Saldanha and Bauchot in Whitehead et al. 1986 ). Circumglobal; western Pacific Ocean north to Japan and Russian North-western Pacific ( Orlov and Tokranov 2019 ); unknown in eastern North Pacific except for one record from south-eastern Bering Sea, Alaska (Mecklenburg et al. 2002), and one record from off Cabo San Lucas, southern Baja California ( Sulak and Shcherbachev 1997 ). Depth: 295–4,855 m ( 968–15,928 ft ) (min.: Orlov and Tokranov 2019 ; max.: Saldanha and Bauchot in Whitehead et al. 1986 ). We classify this species in Histiobranchus following Sulak and Shcherbachev (1997) . Histobranchus cf. bathybius was observed in the Clarion-Clipperton Zone (about 12°27.2’N , 116°38.9’W ), well south of the Cabo San Lucas record ( Amon et al. 2017 ).
