Biologi     Ordlista (t.ex. epibenthic)

Occur in sandy shores and bays, mostly in shallow surf zones, but also to 15 m depth. Often found near rocks and entrances to bays. Usually form small groups, but aggregate for spawning. Pelagic spawners (Ref. 56049). Feed on invertebrates, such as marine worms, clams, crabs and small crustaceans.
