The White-Freckled Surgeonfish is a small to mid-sized tang with a gray to brown body covered in distinctive white spots or freckles, particularly on the head and anterior body. It has the characteristic compressed body shape and venomous spine on the caudal peduncle typical of tangs (Acanthuridae). The body coloration and white marking pattern distinguish it from other surgeonfish species.
