خارهاي باله پشتي (کل): 0; شعاع نرم باله پشتي (کل): 14-17; خارهاي باله مخرجي 0; شعاع نرم باله مخرجي: 20 - 24. Snout pointed, about 3/4 eye diameter; maxilla long, tips pointed, reaching beyond hind border of pre-operculum, almost to gill opening; gill cover canals of panamensis-type. Anal fin origin below about midpoint of dorsal fin base. Anus nearer to anal fin origin than to pelvic fin tips. Silver stripe along flank (a dark line above) of uniform width, narrowed immediately behind band (Ref. 189). Back greenish, some yellowish on head. Melanophores outline all dorsal scales (Ref. 7251).
Forms dense schools, often in shallow waters close to shore. Able to tolerate a wide range of salinities, from hypersaline to almost fresh. Feeds on copepods when young, then on gastropods, foraminifers and an occasional ostracods and annelid. Breeding was recorded in April through to July at Beaufort, North Carolina. Breeds in harbors, estuaries and sounds. Eggs are elliptical, transparent, without oil globule, the yolk appearing `cellular' (Ref. 189). Great variation. Principal parasites are nematodes and cestodes (Scolex polymorphus and Rhynchobothrium sp.) and trematodes (Distomum appendiculatum and Distomum sp). Marketed as food (Ref. 37032).
Spawn in school (Ref. 205).
