Tropical Indo-Pacific
Description
Black spot on pectoral fin base, dark tips on dorsal fin spines, vertical blue streaks on scales and wavy blue lines on fins (less visible in individuals from Japan, which have darker fins and tail). Australian records west of Torres Strait are probably P. limosus, which has a smaller black spot at the base of the pectoral fin instead of the large, obvious black patch in this species.
