Environment: milieu / climate zone / depth range / distribution range
Marine; bathydemersal; depth range 100 - 1200 m (Ref. 559). Deep-water
Pacific Ocean: off southern Japan, Tasmanian Sea, seamounts in the Hawaiian Ridge. Western Central Atlantic: Gulf of Mexico and the Caribbean Sea. Several closely related species may be involved.

Morphology | Morphometrics
(total): 9. Opercular spine present. Gill rakers on the first arch are broader at the proximal end, usually with ridged internal edges (western Atlantic individuals with 26-30, Japanese specimens with 24-32, and Hawaiian Ridge specimens with 30-32). Teeth are developed on the central portion of the tongue but not on its edges (Ref. 31632).
A mesobenthic-pelagic species living mainly above the bottom (Ref. 31632). Found on or near continental slopes and seamounts (Ref. 559).
