Biology     Glossary (e.g. epibenthic)

Adults inhabit neritic waters, often near sandy beaches (Ref. 5217). A shoaling species, generally near the bottom (Ref. 27121). They feed on planktonic invertebrates, primarily copepods, but also on gastropod larvae, ostracods and pteropods (Ref. 3277). Spawning occurs well offshore year-round (Ref. 26938). Eggs are pelagic (Ref. 4233). A good food fish (Ref. 9626). Caught commercially and used mainly for bait.
