Reproduction: anterior dorsal finrays elongated in mature males; spawning apparently prolonged over several months; ovarian eggs about 1.4 mm diameter, with numerous oil globules at maturity (Sanzo, 1938); larvae and post- larvae described and figured by Sanzo (1915, 1938), Taning (1918) and Tortonese (1956); young stages pelagic.
