Morphology | Morphometrics
Dark spot on each side of the snout absent (Ref. 35388).
Inhabits inshore and offshore, although only juveniles appear to occur close inshore. Feeds initially on zooplankton, but for lengths greater than 10 to 15 cm small fish, such as clupeids and ammodytids dominate the diet (Ref. 4674). Spawns in winter and has a more southern distribution (Ref. 35388).
