Biology     Glossary (e.g. epibenthic)

Adults benthopelagic to 650 m depth, juveniles common on reefs (Ref. 34024). At depths of about 40-75 m, adults are found deep on mud and broken shell bottom (Ref. 36413). Smaller silvery specimens taken far out at sea in the epipelagic (Ref. 34024). Caught occasionally (Ref. 34024). Oviparous, with late post-flexion and transformation stage larvae found in midwater (Ref. 36413). Oval, pelagic eggs float in a gelatinous mass (Ref. 205).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Oviparous, with no specialized copulatory organ (Ref. 36413).
