اندازه / وزن / سن
بلوغ: Lm ?  range ? - ? cm
Max length : 14.5 cm TL جنس نر / بدون خواص جنسي; (Ref. 96339)
خارهاي باله پشتي (کل) : 0; خارهاي باله مخرجي: 0; شعاع نرم باله مخرجي: 23 - 32. Snout moderately pointed, about 3/4 eye diameter; maxilla long, tip sharply pointed, reaching to or just beyond gill opening, but shorter and more blunt at 4 to 5 cm standard length; gill cover canals of walkeri-type. Pectoral fins large, tip reaching to beyond pelvic fin base; anal fin origin below dorsal fin origin or a little behind. Silver stripe along flank, as eye in some places.
Body shape (shape guide): elongated; Cross section: oval.
Presumably schooling and most often found in warm, murky waters near shore and in bays near river mouths (specimens taken some km up the Rio Santiago, Nayarit, Mexico). Capable of tolerating lower salinities than that of the sea (Ref. 9298). The ovarian eggs are elliptical. Caught as a by-catch of encircling, lamparo, and trawl nets (Ref. 9298).
