Chinese trumpetfish in shape to the anal fin which is just under. The pelvic fins are located in the middle of the body and are small, with one basal black spot. The body coloration can be uniform or mottled in a range of grey, brown, or dark green. Some fish are uniformly bright yellow. The rear part of the body is normally black with white dots. Two black spots are present on the tail. The compound set of the long caudal peduncle and the caudal fin is yellowish, whatever the fish coloration. Caudal fin usually has two round black spots, at least
Fin and flipper locomotion contracting and relaxing muscles switching roles. They use their fins to propel themselves through the water in this swimming motion. Actinopterygians, the ray-finned fish show an evolutionary pattern of fine control ability to control the dorsal and ventral lobe of the caudal fin. Through developmental changes, intrinsic caudal muscles were added, which enable fish to exhibit such complex maneuvers such as control during acceleration, braking and backing. Studies have shown that the muscles in the caudal fin, have independent activity patterns from the myotomal musculature. These results show specific kinematic roles for different part of the fish's musculature. A curious
