is silvery white. Color Glassy sprats have a unique colour that distinguishes them from other fish of the same species. Its body is mostly black with some silver and translucent portions. There is translucent sprat all the way down their head to the caudal fin, and tiny black dots show irregularly on the back, dorsal and caudal fins, as well as on the lips and chin, and every anal-fin ray has a dark point. Body Structure The larvae of the glassy sprat have an elongated body shape and are ovoid in cross-section. The general body shape of glassy Sprat is side-flat, streamline, fairly elongate, the head of the it is small, however their eyes are big, with large mouth and long branchial cleft. In preflexion larvae, the head is small, but it starts to grow in postflexion and juvenile stages. Glassy sprats have 46-48 myomeres. They have striations on their hindgut, and their gut is long and straight. The swimbladder, which is found midway along their gut, is only inflated in larvae caught at night. The anal opening is a four-fifths distance along the underside of the body and the basal portion of the tail (Prince, 1907). The scales are small and the sidelines are straighter. Their dorsal fins and hip fins are symmetrical, and their tail fin is wedged shape. They do not have dorsal spines and anal spines. The number of their dorsal soft rays, anal soft rays. vertebrae, is 15–16, 19–22, 40-42 respectively. Belly keeled, with 17 + 9 scutes; about 19 dorsal scutes with low keels from head to dorsal fin origin. Second supra-maxilla paddle-shaped, lower portion larger, branchiostegal rays 4. Anal fin origin under or slightly behind base of last dorsal fin ray. The mineralized tissue of its scale is made up of hydroxylapatite, and its mineralized skeleton is composed of apatite. The snout of the glassy sprat is pointed and becomes rounded with growth but is initially dorso-ventrally flattened, and its mouth reaches the anterior of the eye but is moderate in size. There is no head spination, and small teeth can be seen in the jaws from 6.0 mm. Size As the larvae of the glassy sprat start to get older, their bodies start to thicken and become deeper. The usual size of the glassy sprat is the width of the adult's two fingers, and the width of the fish body is about
