The unofficial state
fish of Hawaii. Recognizable by a diamond-shape body with armor-like scales, a dark stripe across their silver sides and belly, and pale blue fins. In addition, they have a sharp,
spike-like dorsal
fin, hence they are commonly known as triggerfish.
Common name: Hawaiian triggerfish
Scientific name: Rhinecanthus rectanglus
Snorkeling in Hanauma Bay one day, I detected several humuhumunukunukuapua'a swimming about. I tried to swim up and
touch one, but it just darted away.
