Body shape (shape guide): fusiform / normal; Cross section: compressed.
Benthopelagic (Ref. 58302). Collected from depths of 6 to 46 m. Sexual maturity at about 12.7 cm. Spawning period occur from February through May. Diet consists mainly of calanoid and cyclopoid copepods, but tunicates, mysids, euphausiids, crustacean larvae, larval polychaetes, siphonophores, and fish eggs are also taken (Ref. 7247). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205).
