Spinescent gill rakers on the first arch with 1 - 3 cusps and many small spines; the angular raker long and triple-rooted. Body entirely scaled at over 20 - 25 cm SL. Pyloric caeca 7 or 8. Color is grayish to copper brown; fins blackish at over 40 cm SL, yellowish with black tips in smaller specimens (the first dorsal fin with a black blotch on two anteriormost membranes); the buccal and branchial cavities are black. Pelvic fin reduced to one spine that becomes entirely absent in specimens more than 40 cm SL.
Found at continental slopes, around oceanic islands and submarine rises (Ref. 6181). Meso-benthopelagic (Ref. 58302). Migrate to midwater at night (Ref. 6181). Feed on fish, cephalopods and crustaceans (Ref. 6181). Eggs and larvae are pelagic (Ref. 6766).
Probably spawns throughout the year in warmer seas.
