Greyish to dark brown in color; young with spots on flanks (Ref. 4410).
Subadults are found near the surface over deep water; juveniles occur inshore from surface waters down to at least 50 m (Ref. 9563). Minimum depth from Ref. 58018. Habitat change gradually occur during the growth of the fish, from epipelagic to benthic (mesobenthopelagic), including talassobenthic. Of no commercial value (Ref. 54802).
