Maturità: Lm ? range ? - ? cm
Max length : 15.0 cm TL maschio/sesso non determinato; (Ref. 7251); common length : 11.5 cm TL maschio/sesso non determinato; (Ref. 12193); Età massima riportata: 2.00 anni (Ref. 12193)
Raggi anali molli: 23 - 26.
Body shape (shape guide): elongated.
Adults feed on copepods, mysids, shrimps, small squids and marine worms (Ref. 7251); also eggs of their own species (Ref. 5951). Preyed upon by striped bass (Ref. 7251) and bluefish (chief predators) (Ref. 5951). Oviparous, eggs are deposited on the substrate during a spawning run along the shore (Ref. 38155). Silversides are sometimes used as live food for trout (Ref. 7251).
