Etymology: Menidia: Greek, menoeides, -es, -es = like a half noon shape (Ref. 45335).
Environment / Climate / Range
Marine; brackish; pelagic-neritic; oceanodromous (Ref. 51243); depth range 0 - 3 m (Ref. 85409). Temperate; 1°C - 33°C (Ref. 35682), preferred 9°C (Ref. 107945); 60°N - 25°N, 82°W - 52°W
Western Atlantic: Gulf of St. Lawrence in Canada to northeastern Florida in USA.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 15.0 cm TL male/unsexed; (Ref. 7251); common length : 11.5 cm TL male/unsexed; (Ref. 12193); max. reported age: 2 years (Ref. 12193)
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).

Phylogenetic diversity index (Ref. 82805
= 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00513 (0.00273 - 0.00965), b=3.09 (2.93 - 3.25), based on LWR estimates for this species & (Sub)family-body (Ref. 93245
Trophic Level (Ref. 69278
): 3.2 ±0.1 se; Based on diet studies.
Resilience (Ref. 69278
