Big, bold and beautiful, the Queen Triggerfish grows up to two feet in size. They have long, dark-blue trailing dorsal, anal and tail fins. The body is olive green to blue with purple to dark-blue accents. The lower half of the head is yellow with two blue stripes from the snout outward to the gill cover. Small black lines radiate from the eyes. Often shy and difficult to approach, a patient snorkeler will be rewarded with a spectacular, full-fin display of this fish.
