Siganus canaliculatus

Body silvery gray above, silvery below; a touch of olive green on nape and upper surface of head; fright pattern mottled with pale cream and dark brown; usually fish display a dark patch just below origin of lateral line. Preopercular angle 89°-96°; cheeks appear to be scaleless but sometimes with few to many, fine, embedded scales on lower 2/3; midline of thorax scaleless between pelvic ridges. Margin of anterior nostril encircled by a low flange with the flap extending towards posterior flap; flap shortens with increasing size. Closely resembles S. fuscescens but differs by its slightly more pointed snout and longer pectoral fins (1.1-1.3 in HL vs. 1.4-1.5 in S. fuscescens) (Ref. 1602). Color pattern is similar to that of S. argenteus and S. fuscescens.
