Appearance
The disk-shaped body is very deep and compressed, and the snout is blunt. There are nine dorsal spines and 21–24 soft dorsal rays, and there are three anal spines and 17–19 anal rays. The second dorsal and anal fins of adults have long, trailing anterior lobes, giving an "angelfish-like" appearance. The body is silver in color with irregular black vertical bands that fade gradually with age. There are four to six black vertical bands on each side, with the first running through the eye and the last running through the caudal peduncle.
