The species grows to about 22 cm and has an elongate, grey-blue body with fine light spots and gold-edged fins; the male has a strikingly blue chin. It often hovers in open water above the reef and snaps at zooplankton drifting by on the current. Like all triggerfish it can lock its first dorsal spine. The fish is harmless to humans.
