Jaw needle fish:
Needlefish with black back and round jaw
Horse-riding fish, Sachauri finfish? (Temminck et al. schlegel, 1846), a small marine fish, belongs to Cephalotaxus, commonly known as Cephalotaxus, Cephalotaxus Japonicus and frozen needlefish.
The pike is slender, with a body length of 17 ~ 24 cm. The upper jaw is triangular, equal in length and width, and the lower jaw extends into a beak shape. The teeth are very small, the body surface is covered with small round scales, and there is a wide emerald vertical belt on the middle line of the back. The dorsal fin is opposite to the gluteal fin, and both are located at the back of the body. The pectoral fin is yellow, the caudal fin is light green, and the lower leaf is slightly longer than the upper leaf. There are many kinds of horse-stepping fish, which are also called "rod fish" and "needle fish" because of their slightly cylindrical shape and needle-like mouth. Most of them are distributed in the western North Pacific.
