The head is small with a short snout and a small, terminal mouth which has small incisor-shaped teeth, there are also teeth on the roof of the mouth and on the tongue. The dorsal and anal fins are not high. The dorsal fin has 10-11 spines and 13-15 soft rays while the anal fin has 3 spines and 12-14 soft rays. The dorsal fin can fold into a sheath. The presence of scales in the interorbital region is an identifying feature. The colour of body is silvery with a bluish shine, marked with 23-29 golden horizontal lines along the body with those above the lateral line curving parallel to it. There is a golden streak below the eye which runs from the snout to just beyion the front edge of the eye. The fins are grey or a slightly darker grey than the colour of the body. The maximum total length recorded is 70 centimetres , although a more common total length is around 50 centimetres (20 in).
