Short description
Claves de identificación | Morfología | Morfometría
Body elongate and somewhat compressed; dorsal profile slightly concave above the eyes; lateral line extending to posterior edge of caudal fin; second anal spine, when folded down, reaching or surpassing origin of caudal fin; pectoral and pelvic fins sub-equal; first gill arch with 26 to 31 gill rakers; back blue gray; belly white; lateral line pale; membranes between dorsal spines and between second and third anal spines pale (Ref. 55763).
Adults are found mainly in estuaries but also enter freshwater to an elevation of 50 m. Diet consists primarily of fish, crustaceans and mollusks (Ref. 36880).
