Western Atlantic: Nova Scotia, Canada (Ref. 7251) southward through the Gulf of Mexico and the Caribbean to Rio de Janeiro, Brazil. Eastern Atlantic: Morocco to South Africa, including the Madeira, Canary, Cape Verde, Ascension and St. Helena islands (Ref. 7097).
Length at first maturity / Size / Weight / Age
Maturity: Lm 11.0  range ? - ? cm
Max length : 30.0 cm SL male/unsexed; (Ref. 3277); common length : 18.0 cm TL male/unsexed; (Ref. 5217); max. published weight: 300.00 g (Ref. 26340)
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.
