Lower jaw extends anterior to upper jaw with a small conical dermal process. Upper jaw with 3 immovable and 3 or 4 movable fang-like teeth anteriorly. Lateral line situated closer to the ventral profile than the dorsal profile posteriorly. Color is silvery with narrow dark dotted lines along the body; the gill membranes are jet-black.
Oceanic, migrating upward at night to 100 to 200 m (Ref. 6181). Probably forming schools during daytime (Ref. 6181). Feed on crustaceans and small fish (Ref. 6181). Females mature at about 16 cm (Ref. 36731). Eggs and larvae are pelagic (Ref. 6766).
