Clupeidae

Common card · No. 468276

Clupeidae is a small family of clupeiform ray-finned fishes, comprising the true herrings and sprats, inhabiting temperate marine habitats in both hemispheres. 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. Due to their small size and position in the lower trophic level of many marine food webs, the levels of methylmercury they bioaccumulate are very low, reducing the risk of mercury poisoning when consumed.
