Biology
Oviparous, paired eggs are laid. Embryos feed solely on yolk [733]. Eggs have horn-like projections on the shell [17086]. Mature gonads are symmetrical in terms of mass, and similar in ovarian follicle number and size (Ref. 58429). Egg laying possibly throughout the year (Ref. 58429). Feeds mainly on amphipod and polychaete (Ref. 54177). As the fish increased in size, polychaetes became important and the importance of amphipods decreased. In larger animals, >40 cm D, isopods and Loligo gahi also increased in importance (Ref. 54177).
