Clupeidae is a family of clupeiform ray-finned fishes, comprising, for instance, the herrings and sprats.Many members of the family have a body protected with shiny cycloid (very smooth and uniform) scales, a single dorsal fin, and a fusiform body for quick, evasive swimming and pursuit of prey composed of small planktonic animals.
Their food is smaller fish and crustaceans . Typically throughout the species, the maximum size is 1 m (3.3 ft) and the maximum weight 10 kg (22 lb). The body is fusiform (tapering spindle shape) and oval in cross-section; being slightly laterally compressed, and the eyes are large and partially covered with adipose eyelids.
Fish have a variety of different body plans. At the broadest level, their body is divided into the head, trunk, and tail, although the divisions are not always externally visible. The body is often fusiform, a streamlined body plan often found in fast-moving fish. Some species may be filiform (eel-shaped) or vermiform (worm-shaped).
As fry, this fish is 5 mm (3 ⁄ 16 in) long, and some of the larger eastern blacknose dace can reach slightly over 100 mm (3.9 in). They tend to live for two or three years and grow continuously during this period. [4] They have a fusiform body shape and the mouth is in a subterminal position.
The species can grow up to 9 cm (3.5 in). They have a fusiform body shape with silvery sides with blue and green lateral iridescent stripes and transparent fins. Their pectoral and pelvic fins are in the abdominal region. They have a pointed snout with a terminal mouth position. The caudal fin is angled inwards to make a forked shape.
Shenacanthus is roughly 2.2 cm (0.87 in) long, with a fusiform body shape like most other jawed fish. It shares many characteristics with chondrichthyans, specifically the posteriorly retracted gills, a lack of dermal bones around the jaw and small diamond-shaped scales.
The pallid shiner is a small silver fish with very little pigmentation on its fusiform body and like most fishes, it is laterally flattened. [5] The only marking on its body is a thin lateral stripe that extends from its head to its tail. The scales on its body are composed of round lateral scales called cycloid scales.
