Europe’s sardine, Sardina pilchardus, belongs to the Clupeidae family of Clupeiformes. Family features in terms of morphology include various types of body shape, from torpedo (almost circular vertical section) to fairly compressed laterally. The species of the Clupeidae family do not carry scales in the head, while the rest of the body is sticky. Some species have abdominal flakes. The lateral line is short and in some species it stops a few scales after the last limit of the head. In some species, it is not completely absent. The teeth are particularly small and are located on the jaws. They carry a short dorsal fin placed towards the center of the body. The abdominal flaps are near the dorsal base, and the rays of all the blades are soft. Some species do not have dorsal and ventral fins.
