The Atlantic silverside (Menidia menidia) ranges from the southern Gulf of St. Lawrence to Florida. Silversides are usually found near the shore and in brackish ponds and estuaries along the coast of Prince Edward Island. The Atlantic silverside is a small fish that is usually no longer than 6 inches. The fish is greyish-green in color on top and translucent white on the underside. The silverside gets its name from the metallic silver strip that runs along both sides of its body.
