It is not a protected animal
The body length is 233-284 mm. The body length is 5.7-5.9 times the body height and 4.4-4.9 times the head length. The head length is 3.6-4.5 times the snout length, 3-3.5 times the eye diameter, and 2.4-2.6 times the eye interval. The body is slightly prismatic, the back and abdomen are wide and slightly protruding, the sides are relatively flat, and gradually taper to the tail. The head is quite short, the back is flat, the sides slope inward and downward, and the ventral surface is very narrow. Kiss short. The eyes are large, set sideways and high, closer to the tip of the snout than to the gill openings. The eyes are widely spaced and slightly concave. The nostrils are large, 2 on each side, located at the edge of the eye. Mouth small, anterior position. The upper and lower jaws are approximately equal in length, and the maxilla is short and completely obscured by the preorbital bones. The teeth are thin, and the upper and lower teeth are in the shape of narrow strips. The operculum membrane is separated and not connected to the isthmus. Gill cover strips 10-12. The round scales are very large and their posterior edges are wavy. The whole body is covered with scales except the tip of the snout. The lateral line is very low, close to the ventral edge, and its rear end does not reach the base of the caudal fin. The base of the dorsal fin is slightly longer than the base of the anal fin. The pectoral fins are well developed and wide. The pelvic fin is large, starting from the posterior edge of the gill opening and about the same distance from the base of the caudal fin. The caudal fin is bifurcated and the lower lobe is longer. The back of the body is bluish black, the lower part is silvery white, the dorsal fin and anal fin are gray, and the pectoral fin and caudal fin are light black. [1]
