Benthopelagic over hard substrates (Ref. 58302). Oviparous, distinct pairing during breeding (Ref. 205).

Western Pacific: Japan. More recently reported from the Chesterfield Islands (Ref. 11897). Reported from the Hawaiian Islands (Ref. 58302).

This species is found in the Western Pacific from Tosa Bay, Kochi Prefecture, Japan, the Kanmu Seamount of the Northwestern Hawaiian Islands, and from the Coral Sea between Australia and New Caledonia (Gomon 2006). Distribution is likely more widespread but there are only a few records of this deep water species.

Western and Central Pacific: Taiwan north to southern Japan; Hawaiian Ridge, Hawaiian Islands; Chesterfield Islands (New Caledonia).
