Snout moderate, about 3/4 eye diameter; maxilla moderate, tip pointed, reaching onto inter-operculum, but not to edge of gill cover; gill cover canals of walkeri-type. Anal fin moderate, its origin usually somewhat before midpoint of dorsal fin base. A silver stripe along flank, about 3/4 eye diameter.
Reportedly common in estuaries and backwaters of bays and occasionally near shores outside bays (Ref. 6792). The fifth most abundant fish taken by various gear in Newport Bay, California; a midwater schooling species caught in bag seine hauls mainly in July and September (Ref. 6361). Oviparous, with planktonic eggs and larvae (Ref. 35602).
